What are the three major components of an engine?
2 Answers
The three major components of an engine are: 1. Crankshaft; 2. Engine block; 3. Cylinder head. The functions of an engine include: 1. Generating power by fully combusting the fuel injected into the cylinders; 2. Determining the vehicle's power performance, fuel economy, stability, and environmental friendliness. The composition of an engine consists of: 1. Valve train; 2. Crank-connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Starting system; 7. Fuel supply system. Engine maintenance methods include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning radiator scale; 4. Regularly removing engine carbon deposits; 5. Periodically replacing the three automotive filters; 6. Maintaining reasonable engine speed.
The three major components of an engine are the crank-connecting rod mechanism, the valve train, and the lubrication system. As a seasoned mechanic with over a decade of experience, I frequently deal with these issues in the workshop. The crank-connecting rod mechanism converts the up-and-down motion of the pistons into the rotational force of the engine, serving as the core of the entire power system. The valve train controls the intake and exhaust through valves, ensuring efficient cylinder charging and exhaust. The lubrication system uses engine oil to reduce friction and prevent overheating and damage to components. Poor coordination among these three components can easily lead to engine failures, such as insufficient lubrication causing crankshaft seizure and sudden engine stalling. During routine maintenance, it's essential to regularly check the oil level and condition, and not delay oil changes too long, as repairs can be troublesome and expensive. In short, understanding these three major components can help you identify issues early. Don’t skimp on maintenance to save money—safety comes first.
