How to install the Mitsubishi V73 generator belt:
Loosen the generator fixing screw and the belt tightness adjustment screw. ?
Push the generator against the engine so that the distance between the pulleys is the shortest, then put the belt on and straighten it. ?
Adjust the belt tightness to the appropriate level and tighten the motor mounting screws and adjusting screws.
The schematic diagram is as follows:
Extended Information
Purpose
1. the timing belt is the upper connection is the timing wheel of the engine cylinder head, and the lower connection is the timing wheel of the crankshaft; the timing wheel is connected to the camshaft. There is a cam on the camshaft and its contact point is. the small rocker arm. The power provided by the timing belt generates pressure, which plays a lifting role.
2. The fThe function of lifting the intake valve is to allow atomized gasoline to enter the cylinder. When the exhaust valve is raised, exhaust gases are vented from the cylinder as the camshaft is recessed. non-convex) When the small rocker arm is in contact with the small rocker arm at the same time, the intake valve and the exhaust valve are closed at this time, the compression ratio is generated, the distributor ignites, and combustion internal starts and generates power!
3. For netizens who don't understand, please read the explanation: Taking a four-cylinder vehicle as an example, its firing order is 1, 3, 4, 2, or it can also start with 1, 2, 4 and 3 cylinders:
The intake valve and the exhaust valve of the first cylinder are both closed to produce internal combustion;
At this time, the intake valve of the second cylinder is almost immediately closed and theexhaust valve is closed;
At this time, the intake valve of the three-cylinder is almost completely open to suck in gasoline, and the exhaust valve is closed; ; Open the door completely to evacuate!
4. The timing belt is a consumable part, and once the timing belt is broken, the camshaft will definitely not work according to timing, this will most likely cause the valve and piston to work. collide and cause serious damage. Therefore, the timing belt should be replaced according to the mileage or time specified by the original manufacturer.
5. During the operation process of the automobile engine, the four processes of air intake, compression, explosion and exhaust continuously occur in the cylinder, and the timing of each step should be consistent with the state of movement and position of the piston. Cooperating with each otherTo coordinate intake, exhaust and piston lift, the timing belt acts as a "bridge" in the engine, transmitting power to the corresponding parts driven by the crankshaft.
6. In order to ensure the stable operation of the timing system, many high-end cars use metal chains instead of belts. Since the vehicle's timing belt breaks, it will damage the internal valves of the engine, which is more harmful. Therefore, most manufacturers require replacement intervals for the timing belt.
7. The timing belt is a rubber component. As the running time of the engine increases, the timing belt and timing belt accessories, such as timing belt tensioner and water pump, etc. become more expensive. to arrive at.
8. Therefore, the manufacturer of any engine equipped with uA timing belt will have strict requirements. Timing belts and accessories should be replaced regularly within the prescribed period. The replacement period varies depending on the engine structure. Generally, it must be replaced when the vehicle has traveled 60,000 to 100,000 kilometers. The specific replacement period should be based on maintenance. of the vehicle. The instructions in the manual shall take precedence.
Reference:
The car's ignition switch has four positions: START, ON, ACC and LOCK: START is connected to the start relay; ON is connected to the main electrical equipment, such as computers and engine instruments, and ACC is connected. connected to auxiliary electrical equipment, such as a radio, LOCK means to lock the car. As the picture shows:
The contactor dThe ignition has four positions: START, ON, ACC and LOCK
