What is the working cycle of a gasoline engine?

The working cycle process of a gasoline engine consists of four strokes: intake, compression, combustion expansion, and exhaust. Below is the relevant introduction: Intake stroke: At this time, the piston is driven by the crankshaft to move from the top dead center to the bottom dead center, while the intake valve opens and the exhaust valve closes. When the piston moves from the top dead center to the bottom dead center, the volume above the piston increases, the gas pressure inside the cylinder decreases, creating a certain degree of vacuum. Since the intake valve is open, the cylinder is connected to the intake pipe, and the air-fuel mixture is drawn into the cylinder. When the piston reaches the bottom dead center, the cylinder is filled with fresh air-fuel mixture and the exhaust gases left from the previous working cycle. Compression stroke: The piston moves from the bottom dead center to the top dead center, with both the intake and exhaust valves closed. The crankshaft rotates under the inertia force of the flywheel, pushing the piston upward through the connecting rod, gradually reducing the gas volume inside the cylinder. The gas is compressed, and the pressure and temperature of the air-fuel mixture inside the cylinder increase accordingly.

What does it mean when the anti-skid light is on in a Mercedes-Benz E260?

Mercedes-Benz E260 anti-skid light indicates a fault in the vehicle's Electronic Stability Program (ESP). Its function is to enhance the vehicle's handling performance while effectively preventing loss of control when the car reaches its dynamic limits. Taking the Mercedes-Benz E-Class 2021 260 Sport as an example, its body dimensions are: length 5078mm, width 1860mm, height 1484mm, wheelbase 3079mm, and fuel tank capacity 66l. The Mercedes-Benz E-Class 2021 260 Sport is equipped with a 1.5T turbocharged engine, with a maximum power of 135kW and a maximum torque of 280Nm, matched with a 9-speed automatic transmission.

What Causes the Noise in the Front of a Car?

Here is a detailed introduction to the reasons for noise in the front of a car: Insufficient rigidity: Insufficient body rigidity can cause deformation of the vehicle during driving, resulting in friction or shaking between the doors and the frame, or friction between steel plates due to welding failure. Some cars may have louder wind noise, which is partly related to the car's design. Loose fastening of body components can also cause noise, which is usually resolved by tightening the screws. Engine compartment noise: The cause of noise in the engine compartment can be determined by the sound. Generally, there are three types: a high-pitched belt squeal, caused by belt slippage; a sharp metal-on-metal friction sound during engine operation, indicating damage to the bearings of the generator, water pump, or power steering pump; and a hissing sound during engine operation, which may be due to a blocked exhaust system or a leaking or broken vacuum tube.

What Causes the Rustling Sound After a Car Drives Through Water?

There are many reasons for a car to make noise after driving through water, mainly including water on the brake pads, foreign objects stuck between the brake pads and calipers, water ingestion in the exhaust pipe, or debris trapped in the chassis. Below are the relevant explanations: Water on the brake pads: If the car drives through shallow water and water splashes onto the brake pads, a squealing sound when braking is normal. This situation will resolve itself as the water dries off with normal driving. Foreign objects on the brake pads: If the car drives through deep water, debris such as plastic bags, paper, or mud may get stuck on the brake pads, causing noise when braking. In this case, the brake pads should be cleaned. Water ingestion in the exhaust pipe: If the car drives through deep water and water enters the engine through the exhaust pipe, it can prevent the proper combustion of fuel and air mixture in the engine, also leading to noise.

How Often Should Car Engine Oil Be Changed Based on Time?

Car engine oil should generally be changed approximately every 6 months. Engine oil, also known as engine lubricant, serves the following functions: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and removing contaminants; 4. Dampening vibrations and cushioning impacts; 5. Preventing rust and corrosion. The steps for changing car engine oil are as follows: 1. Start the vehicle's engine to warm it up; 2. Unscrew the oil drain bolt; 3. Remove the oil filter; 4. Apply new oil to the gasket of the new oil filter; 5. Pour the new oil into the oil pan; 6. Check for leaks under the engine and verify the oil level using the dipstick before starting the engine for testing. Engine oil consists of base oil and additives. The base oil is the primary component of lubricating oil, determining its fundamental properties, while additives compensate for and enhance any shortcomings in the base oil's performance.
