The Difference Between Direct Injection and Multi-Point Fuel Injection

In fact, direct injection engines and multi-point fuel injection engines cannot be directly distinguished as better or worse without specific performance requirements; the choice between them depends on the consumer's individual needs. Direct Injection Engine: A direct injection engine can be understood literally—it involves high-pressure nozzles directly injecting fuel into the combustion chamber to complete the engine's operation cycle. Advantages: Precise fuel control, faster and more immediate throttle response. Disadvantages: Since the fuel is directly injected into the cylinder for combustion, the requirements for fuel quality and intake air quality are relatively higher. Multi-Point Fuel Injection Engine: Multi-point fuel injection has multiple nozzles, making the engine operation process less direct and quick compared to direct injection. Its advantages include: significantly less carbon buildup in the engine compared to direct injection, making maintenance and servicing easier and cheaper. Disadvantages: The fuel delivery system is more complex, affecting fuel efficiency. Below are the differences between multi-point fuel injection and direct injection: Fuel Quality: Direct injection has higher fuel quality requirements compared to multi-point fuel injection, with a compression ratio as high as 12. Cost: Due to the more complex components of direct injection, it is generally more expensive than multi-point fuel injection. This means that for the same car model, the direct injection version will cost more. Fuel Consumption: Direct injection engines consume significantly less fuel than multi-point fuel injection engines. Performance: Direct injection engines provide 10% higher power and torque compared to conventional engines of the same displacement. Technology: Multi-point fuel injection is a more mature technology, while direct injection is a newer and more advanced fuel injection technology. Maintenance: Multi-point fuel injection has a simpler structure, making it easier and more reliable to maintain compared to direct injection. Direct injection engine models are more fuel-efficient, making them suitable for those who drive frequently, as they can save significantly on fuel costs. Multi-point fuel injection is more suitable for those who only occasionally drive for leisure. Choosing a car isn't just about the engine—it requires a comprehensive evaluation based on multiple factors.

How are SUV classes categorized?

China's vehicle classification standards divide SUVs into: subcompact SUV, compact SUV, midsize SUV, full-size SUV, large SUV, and MPV. Below is more detailed information: Compact SUV: Compact SUVs typically have a wheelbase between 2500mm-2700mm and a body length between 4200mm-4600mm. They represent the dominant force in the SUV market, offering significant improvements in space and off-road capability compared to subcompact SUVs. For those seeking a balance between SUV performance, sedan comfort, and fuel efficiency, compact SUVs are undoubtedly the optimal choice that satisfies all three aspects. With stylish exteriors, comfortable interiors, and comprehensive features, they fully meet urban commuting needs as well as holiday off-road adventures. Representative models include: Honda CR-V, Volkswagen Tiguan, etc. Midsize SUV: Midsize SUVs generally feature a wheelbase between 2700mm-2900mm and a body length between 4600mm-4800mm. Their designs exude stability and sophistication while maintaining refined details. Midsize SUVs combine numerous advantages, with their spacious interiors meeting various needs—some models even offer 7-seat configurations. Representative models include: BMW X3, GAC Trumpchi GS8, etc. Full-size SUV: Full-size SUVs usually have a wheelbase between 2800mm-3000mm and a body length between 4800mm-5000mm. Compared to midsize SUVs, they provide not only more interior space but also more luxurious features, stronger power outputs, superior off-road performance, and enhanced safety. Representative models include: Toyota Prado, Land Rover Range Rover, Zotye T700, etc. Large SUV: Typical large SUVs are characterized by the American SUV style—high-displacement engines, massive dimensions, and expansive interiors. Evolving from station wagons, they combine sedan-like comfort, the generous passenger space of wagons, and the utility of vans.

What are the standard dimensions for reverse parking (garage entry)?

The standard dimensions for reverse parking garages are as follows: For small cars: length 5.25 meters, width 2.3 meters. For large vehicles: length 15.9 meters, width 6.83 meters. The evaluation criteria for reverse parking: Failure to follow the prescribed route or sequence results in disqualification; vehicle body crossing the line results in disqualification; failure to fully enter the garage results in disqualification; stopping midway results in disqualification; exceeding 4 minutes results in disqualification. Reverse parking rhyme: Reversing in and out isn't hard, fasten belt, shift gear, left signal flash. Press clutch, release handbrake, slowly lift clutch for gentle start. Watch right line to adjust car body, left mirror seam follows right line. Stop when front line aligns with shoulder, shift to reverse, release clutch. When left mirror covers corner line, turn wheel fully right. Watch left mirror for garage line, at 30-degree angle turn back one round, when car parallels line, straighten wheel two full turns. When left mirror covers front garage corner, press clutch and brake. Shift to first gear to exit, turn wheel fully left when bumper touches line. Stop when hood covers line, keep wheel position to reverse. Watch right mirror for garage line, at 30-degree angle turn back one round, when car parallels line, straighten wheel two full turns, when left mirror covers front garage corner, press clutch and brake. Shift to first gear to exit, turn wheel fully right when bumper touches line. Stop when hood covers line, adjust car body with high skill. The new garages have no poles for reference, only ground markings. The garage length is much shorter than current standards - just enough to fit a car completely. The process involves reversing in from the right, driving out and turning left, then reversing back in, finally driving out to return to start point. This simplified process eliminates the current exam's garage transfer step.

What is the Difference Between a Motorcycle Pushrod Engine and a Chain-Driven Engine?

The biggest difference between a motorcycle chain-driven engine and a pushrod engine lies in their valve systems. The pushrod engine features a lower-mounted camshaft, where the valve opening and closing are controlled by pushrods. In contrast, the chain-driven engine has an overhead camshaft, with the crankshaft driving the camshaft and rocker arms via a timing chain to operate the valves. Comparatively, chain-driven engines are quieter, produce less vibration, offer faster acceleration, and have better environmental performance than pushrod engines, making them superior. However, this design has two drawbacks: the camshaft can only transmit motion to the intake and exhaust valve mechanisms at the top of the engine through additional components (pushrods), and the camshaft in the crankcase is inconvenient to maintain. If timing adjustments are needed, the entire engine must be disassembled. To address these issues, the solution is to position the camshaft at the top of the engine, integrating it with the intake and exhaust valves to form a complete valve train. However, as the distance between the camshaft and the crankshaft increases, using simple gear meshing becomes impractical. The solution is to employ a chain or belt for transmission. The advantage of chain transmission lies in its precision compared to belt drives. The primary benefit of a chain-driven engine is its high transmission accuracy. Since the camshaft's angle and the opening and closing of the valves are defined by the crankshaft's angle, precise control of their angular relationship is essential. Chains meet this requirement perfectly and do not require frequent replacement. Although belt drives can also ensure precision, belts tend to stretch over time due to tension, necessitating regular replacement. The downside of chain drives is that they are noisier and more expensive to manufacture than belt drives, which is why manufacturers now prefer belt drives. Ultimately, it is difficult to definitively say which is better, as it depends on individual needs and preferences.

Do I need to apply for a card for ETC?

Yes, you need to apply for a card. You can do so at bank branches or highway service areas. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. You will also need to fill out a Postal Savings credit card application form, which will be used to bind the ETC card. After receiving the credit card, make two transactions with it and present the POS receipts to designated Postal Savings outlets to receive and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old and own the vehicle in their name. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway toll fees is also required. Applicants must be between 18 and 60 years old and own the vehicle in their name. Here are some considerations for installing ETC: Do not obstruct the driver's view; it is best to install it behind the rearview mirror: Many car models have steeply angled windshields, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or in positions that might block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. Once the electronic tag is installed, the windshield will press the anti-tamper lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This feature is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its ETC device malfunction, maintain a distance of at least 10 meters from the vehicle ahead. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failure to read the vehicle's device information and toll deduction failure. If a debit card is used to bind ETC, insufficient balance will also cause toll deduction failure.
