What Are the Components of a Car Engine?

Car engines consist of five major systems and two main mechanisms. The five systems are: the fuel supply system, cooling system, lubrication system, ignition system, and starting system. The two mechanisms are: the crankshaft-connecting rod mechanism and the valve train. An engine is not a single unit; from top to bottom, it includes the valve cover, cylinder head, cylinder block, and oil pan, with sealing gaskets between these parts. The engine is often referred to as the heart of the car, responsible for providing power. There are various types of car engine cylinders, such as inline cylinders, V-type cylinders, W-type cylinders, and horizontally opposed cylinders.

Can You Stop During the Subject 2 Driving Test?

Subject 2 Driving Test allows stopping throughout the process as long as it does not involve illegal parking. The precautions for the Subject 2 slope fixed-point parking and starting are as follows: Choose marking points: Use the center line of the car hood as a marker, and try to adjust the vehicle to be parallel to the lane lines on both sides; use the marking pole at the lower right corner of the front windshield and the right side of the solid line on the slope as the two main marking points. When driving to the slope: Look through the front windshield, and when the marking pole is 25 to 30 centimeters away from the lower right corner of the front windshield, brake and then pull the handbrake. When starting on the slope: Press the clutch and shift into 1st gear, slowly lift the clutch—lifting it too quickly may cause the vehicle to stall. When you feel the vehicle's shaking is at its maximum, keep the clutch position steady, release the handbrake, and the vehicle will start.

What is the reason for frequent stalling when turning with a manual transmission?

This is due to insufficient driving skills and lack of proficiency in coordinating the clutch and throttle. Here is relevant information: 1. Gear adjustment: For automatic transmissions, gear changes should be performed progressively one by one, with the shift timing determined by the actual engine speed. The automatic transmission can only shift gears when reaching the specified RPM. For manual transmissions, gear changes can be made manually even when the RPM is insufficient, allowing for faster speed control, handling, and response compared to automatic transmissions. This is why most supercars use manual transmissions. 2. Introduction: A manual transmission is a type of gearbox and the most basic form of automotive transmission. Its function is to change the gear ratio (also called the gear ratio), utilizing the principle of torque leverage by using the largest diameter low-speed gear with the longest radius to amplify engine torque, assisting the vehicle in starting forward movement.
