JAC Jiayue A5 is equipped with a 1.5-liter turbocharged four-cylinder engine across the entire lineup, with the model number HFC4GB2.4E. This engine delivers a maximum power of 110 kW and a maximum torque of 210 N·m. It features VVT technology and multi-point electronic fuel injection, and utilizes an aluminum alloy cylinder head and block. The engine in the JAC Jiayue A5 is domestically produced, developed and manufactured by JAC Motors. For daily maintenance of the JAC Jiayue A5 engine, the following methods can be employed: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD to SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB to CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Periodically clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. In small amounts, the sludge remains suspended in the oil, but in larger quantities, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates smoothly but also extends the overall lifespan of the radiator and engine.

Why does driving over a stone make a loud bang?

Driving over a stone and hearing a loud bang is the sound of the stone colliding with the tire. Avoid driving on bumpy roads: When using your car, try to avoid deep potholes, and always slow down when driving over uneven surfaces or speed bumps. This reduces the impact on the suspension system. Driving over bumpy roads or speed bumps may alter the car's wheel alignment data, so it's important to regularly check and adjust the wheel alignment. Incorrect wheel alignment can lead to uneven tire wear or the car pulling to one side. Car shock absorbers: The shock absorbers in a car are wear-prone components. While they generally last a long time, their performance degrades over time. If you hit a large stone and hear a loud noise, it might be coming from the shock absorber. In some cars, shock absorbers may also start leaking oil as they age.

What does the car tire size 235/55/17 represent?

The car tire size 235 represents a tire width of 235mm, 55 indicates that the aspect ratio (height to width percentage) is 55%, and R17 denotes a wheel rim diameter of 17 inches. Tire Introduction: Tire types follow international standard tire codes, expressed in millimeters for section width and as a percentage for the aspect ratio. This is followed by the tire type code, rim diameter (in inches), load index (permissible load-carrying capacity code), and permissible speed rating code. Front and Rear Tires: Most sedans have identical front and rear tire specifications. However, in some high-performance vehicles like sports cars or rear-wheel-drive models, front and rear tire sizes may differ. Generally, vehicles with larger engine displacements tend to have larger tire specifications, which directly affect the car's comfort, aesthetics, and off-road capability.

What is the fuel consumption of Cummins?

The fuel consumption data for Cummins is approximately 14-16 liters per 100 kilometers. Main factors affecting fuel consumption: Unnecessary increase in vehicle load: Many new car owners tend to load their cars with various decorations and exterior accessories, and some even move their office and home into the car. Blindly adding body kits, spoilers, winches, and roof racks to the car will also increase fuel consumption. Frequent braking and starting: Apart from factors like car design and engine, the real waste of fuel comes from the driver's habits. Frequent sudden braking and rapid acceleration are the biggest causes of increased fuel consumption. An experiment once showed that the same car driven by different drivers resulted in the novice driver's fuel consumption being twice as high as that of an experienced driver. This demonstrates how important good driving habits are for saving fuel.

What are the symptoms of a motorcycle engine misfiring?

Motorcycle engine misfiring symptoms include severe engine vibration. Specific manifestations of motorcycle misfiring: Observe the exhaust pipe outlet; the exhaust gas flow shows obvious intermittency, accompanied by severe exhaust pipe vibration, and a distinct "popping" sound can be clearly heard. The main symptom of misfiring is severe engine vibration. This occurs because one or more cylinders are not functioning, disrupting the engine's balance. When the crankshaft reaches a point where a cylinder should ignite and produce force to push it, the absence of this force causes the speed to drop. When the next cylinder ignites and provides thrust, the speed increases, leading to unstable RPM and engine vibration. Causes of motorcycle misfiring: The most common cause of motorcycle misfiring is a damaged spark plug, which fails to ignite, preventing the cylinder from burning and resulting in misfiring. Another possible cause is a faulty fuel injector, which either fails to spray fuel or sprays poorly atomized fuel, leading to incomplete combustion and misfiring.

What is the width of a two-lane road?

The minimum width of a two-lane road is above 6 meters. Two-lane roads in China: In China, second-class and third-class roads are generally designed as two-lane roads. For second-class roads in plain and hilly areas with heavy mixed traffic, it may be difficult to separate slow lanes. In such cases, lanes can be marked for fast and slow traffic, but they are still considered two-lane roads. Fourth-class roads should be designed as two-lane roads, but single-lane sections can be used for areas with light traffic. Precautions for driving on two-lane roads: When the road is narrow or there are obstacles on the roadside, driving becomes more challenging. In such situations, it is important to remain calm, control your speed, and avoid driving too fast. Always observe the road carefully. If there are obstacles ahead and oncoming traffic in the opposite lane, large trucks should slow down or even stop temporarily to allow smaller vehicles to pass safely. Never compete for the right of way to ensure safety.

What is the normal tire pressure for a Mercedes-Benz C-Class, and where can it be checked?

The tire pressure information for the Mercedes-Benz C-Class can be viewed in the tire pressure check module located in the center of the dashboard. According to the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar. In winter, the tire pressure should be adjusted slightly higher by about 0.2 bar based on the standard tire pressure. In summer, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will alert if the pressure is generally below 1.8 bar or above 3.0 bar. In such cases, tire inspection and pressure adjustment are necessary. Tire pressure monitoring not reset: If the tire pressure is not reset promptly after inflation, the system will still record the previous data, causing the tire pressure monitoring indicator to light up. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new component.
