What is the Difference Between Transverse and Longitudinal Engine Layouts?

Transverse and longitudinal engine layouts differ specifically in terms of the placement direction of the engine and transmission, the direction of power output, the vehicle's drive system, and the suspension system. Normally, car engines are placed in the front engine compartment. If the engine crankshaft axis is aligned in the same direction as the wheel half-shaft axis, it is a transverse layout. If the engine crankshaft axis is arranged perpendicular to the wheel half-shaft axis, it is a longitudinal layout. Placement direction of engine and transmission: A transverse engine is placed horizontally, requiring the transmission to be placed horizontally alongside it. A longitudinal engine is placed vertically, with the transmission positioned behind the engine. Direction of power output: The power transmission direction of a transverse engine is typically perpendicular to the vehicle's forward motion. After entering the transmission, the power is usually transmitted laterally directly to the half-shaft. The power transmission direction of a longitudinal engine is parallel to the vehicle's forward motion, transmitting backward. After entering the transmission, the power continues to be transmitted longitudinally backward, often connecting to an intermediate drive shaft for direct rearward transmission. Vehicle drive system: Transverse engines are typically used in front-wheel-drive vehicles, while longitudinal engines are commonly found in rear-wheel-drive vehicles. Suspension system: Vehicles with a longitudinal engine layout require less horizontal space, allowing for more room to install advanced multi-link or double-wishbone suspension systems. In contrast, transverse engine layouts, due to the longer engine length and the need to place the transmission alongside, demand more horizontal space. As a result, transverse engine layouts often use the more economical MacPherson strut suspension for the front suspension.

Does the Geely Jiaji have a 4-cylinder engine?

Geely Jiaji has a 4-cylinder model, which is equipped with a 1.8t engine, while the 1.5t engine model is a 3-cylinder engine. The relevant introduction of the 4-cylinder engine is as follows: Working principle of the 4-cylinder engine: It usually converts chemical energy into mechanical energy. Sometimes the engine is not only applicable to the power generation device, but also refers to the entire machine including the power device, such as gasoline engines and aircraft engines. The main part of the engine is the cylinder, which is the power source of the entire car. Purpose of the 4-cylinder engine: The 4-cylinder engine body is mainly composed of cylinder block, crankcase, cylinder head and cylinder gasket. Main uses: mostly used in car engines, motorcycles, chainsaws and other small power machinery.

What are the reversing techniques?

Here is an introduction to reversing techniques: 1. Adjust the position between the car body and the corner of the garage: When reversing for the first time, lean forward to check the right rearview mirror in advance to observe the positional relationship between the car body and the corner of the garage. Predict whether the car body will be too close or too far from the corner of the garage based on the angle observed in the rearview mirror, then steer to correct it. It is best to maintain a distance of 30 centimeters between the car body and the corner of the garage. 2. Correct the car body inside the garage: After the rear half of the car body enters the garage, steer to adjust. Observe the left and right rearview mirrors to determine which side the front of the car is leaning towards and which side the rear is leaning towards, then steer towards the side the front is leaning to correct the car body. 3. Find the right stopping point: Judge when to stop by observing the relationship between the left rearview mirror and the side line. When the left rearview mirror covers the side line, immediately press the clutch to stop.

What are the differences between medium-sized buses and large buses?

The differences between medium-sized buses and large buses are as follows: 1. Passenger capacity: Vehicles with a seating capacity of more than 9 but fewer than 20 people are classified as medium-sized passenger vehicles; those with a certified capacity of more than 19 people are classified as large buses. 2. Driver's license level: A Class A1 license is required to drive large buses; according to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' drivers holding a Class B1 license are permitted to operate medium-sized passenger vehicles. 3. Vehicle length: Vehicles shorter than 6 meters are classified as medium-sized passenger vehicles; large urban buses (10-12 meters) and extra-large urban buses (articulated buses are 13-18 meters, double-decker buses are 10-12 meters with two levels of seating).

How Many Kilometers Should a Volvo Timing Belt Be Replaced?

Volvo timing belts should be replaced between 90,000 to 100,000 kilometers. Below is relevant information about the function of timing belts: 1. Driving the Valve Train: It drives the engine's valve train. Even those with shorter usage periods should not exceed 100,000 kilometers. When replacing, use genuine or major brand products and opt for complete sets to ensure performance. During replacement, strictly adhere to the torque parameters of each component to meet the original factory specifications. The generator and compressor belts can be replaced at the same time. 2. Opening and Closing Exhaust Valves: It ensures the engine's intake and exhaust valves open and close at the appropriate times. 3. Enabling Normal Cylinder Intake and Exhaust: It guarantees that the engine cylinders can intake and exhaust air normally.

Why Should Motor Vehicles Slow Down in Rainy Weather?

Because the road is slippery in rainy conditions, the braking distance increases, and visibility is reduced, motor vehicles should slow down when driving in the rain. Below are precautions for driving in rainy weather: 1. Maintain good visibility: In addition to driving cautiously, promptly turn on the windshield wipers and use low-beam headlights and fog lights when the weather is dim. 2. Prevent wheel skidding: Rainwater on the road forms a "lubricant" between the tires and the road surface, reducing the vehicle's braking performance and increasing the risk of skidding. 3. Drive slowly in low gears: Regardless of road width or condition, use second or third gear when driving in the rain, keeping the speed below 30 or 40 km/h, and be mentally prepared to take emergency measures. 4. Avoid getting stuck in water: When encountering flooded roads, such as under overpasses or deep tunnels, first stop to check the water depth. If the water exceeds the exhaust pipe, it may cause the vehicle to stall; if it exceeds the bumper, water may enter the vehicle. 5. Do not restart the vehicle after stalling: If the engine stalls due to water, do not attempt to restart it. Instead, leave the vehicle in place and wait for a tow. 6. Maintain safe following distance: Do not follow large vehicles too closely, as they block visibility, and a path passable for large vehicles may not be passable for smaller ones. 7. Watch for pedestrians: Pedestrians holding umbrellas and cyclists wearing raincoats have limited visibility, hearing, and reaction time. 8. Turn on lights promptly: In heavy rain with extremely low visibility, turn on the headlights, position lights, and taillights, and move the vehicle off the road or park it in a safe place.
