What Causes Engine Failure in a Car?

1 Answers

The reasons for engine failure in a car are as follows: 1. Sensor-related failures: such as the water temperature sensor, crankshaft sensor, oxygen sensor, etc.; 2. Poor combustion of the air-fuel mixture: issues with the engine's spark plugs, ignition coils, fuel pump, or clogged fuel lines can all lead to poor combustion of the engine's air-fuel mixture. 3. Air intake problems: The engine requires air intake during combustion, and in this process, the air filter is crucial. If the car's air filter is dirty and not cleaned regularly, it can affect the car's air intake. Over time, this can lead to blockages, and in severe cases, it can cause the engine warning light to illuminate. 4. Turbocharging issues: Problems with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust pipe.

Can You Use Windshield Wipers After Applying Car Window Film?

You can use windshield wipers after applying car window film because the wipers are located on the exterior of the front windshield, while the film is applied to the interior. There is no contact between the two. The functions of car window film include: 1. Blocking heat generated by infrared rays; 2. Filtering ultraviolet rays to protect the skin; 3. Enhancing safety and explosion resistance, as the film is highly resistant to tearing and penetration; 4. Maintaining privacy and security; 5. Reducing air conditioning load; 6. Minimizing accidents caused by glare. The installation method for car window film is as follows: 1. Protect the vehicle's interior; 2. Cut the film according to the window dimensions; 3. Clean the front and rear windshield glass; 4. Use a heat gun to shape the film; 5. Perform fine trimming after heating the film.

How to Determine if a High-Pressure Fuel Pump is Good or Bad?

To determine if a high-pressure fuel pump is good or bad, observe the following symptoms: severe vehicle shaking, weak acceleration, unstable idle, difficulty starting, or engine stalling, which indicate a damaged high-pressure fuel pump. The functions of a high-pressure fuel pump are: 1. It increases fuel pressure to ensure complete combustion; 2. It enables high-pressure injection for optimal atomization; 3. It serves as a power source for hydraulic devices such as jacks, headers, extruders, and cotton gins. Causes of high-pressure fuel pump damage include: 1. Improper refueling practices; 2. Avoid waiting until the fuel warning light comes on before refueling, as this shortens the pump's lifespan; 3. Running the fuel tank too low or completely out of fuel can burn out or damage the pump; 4. Overfilling the fuel tank.

The models under Lexus include: Lexus GS, Lexus ES, Lexus LS, Lexus IS, Lexus UX, etc. Taking the 2017 Lexus GS as an example, it is a mid-to-large-sized car with body dimensions of: length 4880mm, width 1840mm, height 1455mm, and a wheelbase of 2850mm. The 2017 Lexus GS is equipped with a 2.0T inline 4-cylinder turbocharged engine, with a maximum horsepower of 245PS, a maximum torque of 350Nm, and a maximum power of 180kW, paired with an 8-speed automatic transmission.

What to Do When the Built-in Tire Pressure Monitoring Sensor Runs Out of Battery?

The solution for a built-in tire pressure monitoring sensor running out of battery is to directly replace the sensor module. The functions of tire pressure monitoring are: 1. It alerts promptly in case of fast or slow air leakage when the tire is punctured; 2. It warns when tire loosening causes unbalanced friction, leading to tire temperature reaching 70 degrees Celsius to prevent blowouts; 3. It alerts when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing tire temperature rise and blowouts. The method to reset the tire pressure monitoring is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a flat surface and turn off the engine; 3. Power on the vehicle, hold down the tire pressure monitoring button, and after 5 seconds, a warning sound will be heard—release the button to complete the reset successfully.

Do electric vehicles require annual inspections?

Electric vehicles require annual inspections. Here are the relevant details: Vehicle types: Both pure fuel-powered vehicles and electric vehicles need to undergo on-site inspections after 6 years of use. For vehicles between 6 to 15 years old, inspections are required once a year. After 15 years of use, inspections are required every six months. Inspection items: The main difference between fuel-powered vehicles and pure electric vehicles lies in the inspection items. Pure electric vehicles do not require on-site inspections for exhaust emissions testing. However, other functional inspections such as lights, appearance, and chassis are still required for pure electric vehicles. After passing the annual inspection, pure electric vehicles, like fuel-powered vehicles, must display the annual inspection sticker on the windshield to prove that the vehicle has passed the annual inspection for that year.

What to Do About a Rusty Exhaust Pipe?

The solutions for a rusty exhaust pipe are: 1. Use ultra-fine water sandpaper dipped in water to sand off the rust spots; 2. Apply a layer of primer; 3. Once the primer is dry, sand it smooth with water sandpaper; 4. Use a touch-up paint pen for coloring. Methods to prevent exhaust pipe rust include: 1. Spraying anti-rust materials; 2. Drilling holes at the tail of the exhaust pipe; 3. Replacing it with a stainless steel exhaust pipe. Exhaust pipe maintenance tips: 1. Waterproofing: When driving in the rain or going to a car wash, be careful to prevent water from entering the muffler, which can cause rust and affect the exhaust pipe's performance; 2. Rust prevention: Remove the muffler, block the drainage hole, add anti-rust oil evenly into the cylinder, and reinstall the muffler; 3. Cleaning: The exhaust pipe is often exposed to the outside, similar to the car's interior. Internal dirt buildup can hinder normal operation, so it's important to keep the exhaust pipe clean.
