BJ493ZLQ3G engine
The BJ493ZLQ3G engine is a gasoline engine known for its high efficiency and low emissions. It has a small gas tank for holding gas and gas passages that transport gasoline to the engine's cylinders. The ignition occurs due to the gas and air mixture in the cylinders and sparks from the spark plugs. The pistons are pushed by the combustion of the gas-air mixture, which also rotates the crankshaft. Engine power is transmitted to the vehicle through the transmission system. The BJ493ZLQ3G engine also has a cooling system that uses coolant to cool the engine and a lubrication system that uses oil to reduce friction between moving parts.
BJ493ZLQ4 engine
The BJ493ZLQ4 engine is a dual-fuel engine that operates on both diesel and natural gas. It has a large gas tank for holding gas and a gas supply system that ensures the safe and efficient delivery of gas to the engine. The BJ493ZLQ4 engine also has a gas mixture control system that regulates the gas-diesel mixture entering the cylinders. The engine's ignition is triggered by the diesel fuel, which is ignited by compression in the cylinders. The combustion of the gas-diesel mixture powers the pistons, which then turn the crankshaft and drive the vehicle via the transmission system. The BJ493ZLQ4 engine also has a cooling system that uses coolant to cool the engine and a lubrication system that uses oil to minimize friction between moving parts.
The following are the specifications of the BJ493ZLQ3 engine:
Cooling Method
The BJ493ZLQ3 engine uses the water cooling method. The water cooling system uses water to absorb heat from the engine and transfer the heat to the radiator, where the water is cooled before circulating back to the engine. Thus, it maintains a uniform temperature.
Fuel Type
The BJ493ZLQ3 engine uses diesel fuel. Diesel engines are more fuel-efficient and have higher torque output compared to petrol engines.
Engine Layout
The BJ493ZLQ3 engine has an in-line engine layout, meaning that all the cylinders are arranged in a straight line. This layout is simple and compact, making it easier to manufacture and more cost-effective.
Number of cylinders
The BJ493ZLQ3 engine has four cylinders. The number of cylinders in an engine affects its power output and efficiency. Engines with more cylinders have higher power output and are more fuel-efficient.
Bore and Stroke
The BJ493ZLQ3 engine has a bore size of 93 mm and a stroke length of 102 mm. The bore and stroke affect the engine's displacement and performance. A larger bore and stroke increase the engine's displacement, leading to higher power output.
Compression Ratio
The BJ493ZLQ3 engine has a compression ratio of 18:1. The compression ratio affects the engine's efficiency and emissions. Higher compression ratios increase the engine's thermal efficiency and reduce emissions.
Lubrication System
The BJ493ZLQ3 engine has a forced lubrication system. The lubrication system reduces friction and wear between the moving parts of the engine. It also transfers heat away from the engine parts and prevents rust and corrosion.
Firing Order
The firing order of the BJ493ZLQ3 engine is 1-3-4-2. The firing order affects the engine's smoothness, power output, and emissions. The firing order is designed to ensure even power delivery and reduce vibrations.
Intake and Exhaust Valves
The BJ493ZLQ3 engine has one intake valve and one exhaust valve per cylinder. The intake valves control the amount of air and fuel entering the combustion chamber, while the exhaust valves control the exit of exhaust gases from the combustion chamber.
Valve Actuation
The BJ493ZLQ3 engine uses a camshaft for valve actuation. The camshaft is connected to the crankshaft, and its rotation opens and closes the valves at the right time during the engine's power stroke.
Fuel Supply System
The BJ493ZLQ3 engine has a direct fuel injection system. In diesel engines, high-pressure diesel is injected directly into the combustion chamber through the fuel injectors. The direct fuel injection system improves combustion efficiency, reduces emissions, and increases engine power output.
Cooling System
The BJ493ZLQ3 engine uses a cooling system that uses a water-cool method. The water-cool method involves circulating water through the engine block to absorb heat and then transferring the water to a radiator, where the water is cooled before circulating back to the engine block.
Engine Control Unit
The BJ493ZLQ3 engine has an electronic control unit (ECU) that controls and monitors the engine performance. The ECU optimizes the engine's fuel efficiency, emissions, and power output based on the input from various sensors.
