What Causes Engine Start-Stop Shaking?

Automatic start-stop shaking during activation is caused by the momentary vibration when the engine starts, which is a normal occurrence. Engine start-stop light keeps flashing: This may be due to a faulty clutch switch or damaged battery negative sensor. It is recommended to have it inspected and repaired at a 4S shop as soon as possible. The engine start-stop technology is a system that automatically shuts off the engine when the vehicle comes to a temporary stop during driving. Does engine start-stop harm the vehicle? Generally, it does not harm the vehicle. The automatic start-stop function allows the engine to shut off automatically during temporary stops and restart automatically when starting, thereby reducing fuel consumption. Over 80% of engine wear occurs during cold starts and operation, while less than 20% of wear occurs during normal driving.

Is it necessary to apply silicone grease to spark plugs?

Spark plugs can be optionally coated with silicone grease, which is applied to the threaded portion of the spark plug. The purpose of applying insulating silicone grease is to provide insulation and prevent the rubber part of the high-voltage coil from conducting electricity. Spark plugs are mainly composed of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but over the past decade or so, engines in most passenger cars have been modified to connect the ignition coil directly to the spark plug. Damaged spark plugs may exhibit the following symptoms: difficulty starting, reduced power, excessive exhaust emissions, and increased fuel consumption.

What Causes Insufficient Engine Vacuum?

Insufficient engine vacuum may be caused by loose vacuum tube clamps, damaged vacuum hose clamps. If the hoses are intact, it could be due to blockage or malfunction of the engine's vacuum suction port. Engine vacuum is formed by insufficient compression, primarily requiring checks for piston ring wear or valve wear leading to air leaks. Engine vacuum generally refers to the pressure difference between the intake manifold and atmospheric pressure. Uses of vacuum: Provides the necessary negative pressure for the brake booster pump (except for electro-hydraulic brakes and electric vacuum pumps); supplies required negative pressure for the steering pump (except for electric steering pumps); facilitates crankcase ventilation circulation; and extracts fuel vapors from the carbon canister. Vacuum level: The degree of gas rarefaction under vacuum conditions is typically indicated by the vacuum level. If the measured pressure inside the equipment is below atmospheric pressure, a vacuum gauge is required for pressure measurement. The reading obtained from the vacuum gauge is called the vacuum level. The vacuum level value indicates how much the system's actual pressure is below atmospheric pressure.

Do Manual Transmission Cars Have Transmission Computers?

Manual transmission cars are equipped with an ECU. The ECU, commonly known as the vehicle's onboard computer, enables the transmission, engine, and various systems to function more efficiently. Introduction to the ECU: The ECU is typically installed in the engine compartment or the central control panel of the car. Its exact location may vary depending on the vehicle brand and model. However, the functionality of the ECU is largely the same across all vehicles, with minor differences in tuning. Features of the ECU: The ECU is designed to withstand high temperatures and vibrations. It can operate in ambient temperatures ranging from -40°C to 80°C and endure vibrations below 1000Hz. The ECU is highly durable and generally requires no maintenance during regular use. As a critical component of the vehicle, the ECU is covered by strict warranty services provided by 4S stores. However, if the owner modifies the ECU to enhance the vehicle's power output, the warranty service may be voided. Modifying the ECU has both advantages and disadvantages—while it can increase power and reduce fuel consumption, it may also shorten the engine's lifespan.
