How to Detect Engine Misfire in a Car?

When the car exhibits noticeable body vibration at idle, weak acceleration with body vibration at low RPM, reduced vibration at high RPM, or lower temperature on the spark plug insulator ceramic when touched by hand, it indicates engine misfire. The relevant details are as follows: 1. At idle, the body vibration is obvious. Observe the exhaust pipe outlet—the exhaust gas flow shows clear intermittency, accompanied by severe exhaust pipe shaking and distinct "popping" or thumping sounds. 2. At low RPM (around 2000), the body vibrates noticeably with weak acceleration, while the vibration diminishes at higher RPM. This phenomenon is often related to the ignition coil. Open the engine hood and observe the running engine: if it exhibits significant abnormal shaking (beyond normal operational vibration with large amplitude), you can begin checking for misfire. 3. After turning off the engine, touch the insulator ceramic of each spark plug by hand (cylinder 1 in a 4-cylinder engine is harder to reach). If a cylinder's temperature is lower, it indicates abnormal operation. You can also use a screwdriver to short-circuit the spark plug or disconnect the cylinder wire for a cut-off test. If the engine operation shows no significant change after disconnection, it confirms the cylinder is not working. A car missing one or two cylinders can still start.

What is the method for changing engine oil by yourself?

First, use a jack to lift the vehicle, then unscrew the oil drain plug to drain the oil, replace the oil filter and gasket, and finally add the appropriate new engine oil in the engine compartment. The steps for changing engine oil by yourself are as follows: 1. Preheat before changing the oil: Use a jack to lift the vehicle, and it's best to prepare wedge-shaped wooden blocks for support to prevent the jack from slipping. 2. Locate the oil drain plug, unscrew it to drain the oil, and be cautious of the oil temperature to avoid burns: Allow the oil to drip for a while to ensure thorough drainage. Do not overtighten to prevent damage to the oil pan. 3. Unscrew the filter and place a container beneath it: Observe the filter carefully, and wear gloves if the temperature is too high. Be careful not to damage the filter mounting screw or the components around the filter. 4. Select the appropriate oil filter. 5. Apply new engine oil to the gasket of the new filter, then screw and tighten the filter (usually tighten it and then turn it an additional 3/4 turn). 6. Next, add new engine oil. To prevent oil from spilling outside the engine, you can use a funnel. After adding the oil, check for any leaks underneath the engine. If everything is normal, check the oil dipstick and then start the engine.

How to Maintain the Fuel System?

Automotive fuel system maintenance includes: fuel pump, fuel lines, filter, fuel rail, fuel injectors, fuel pressure regulator, etc. Regular use of fuel additives for cleaning is sufficient. For new vehicles, it is generally recommended to add protective agents when cleaning the fuel system at around 50,000 kilometers. Fuel system maintenance includes: 1. The fuel system consists of the fuel tank, fuel lines, and fuel injectors, with components such as the fuel pump and fuel filter in the system. Fuel enters the combustion chamber through the fuel pump, fuel filter, and fuel injectors to burn and generate power; 2. The fuel lines are filled with gum formed by fuel oxidation. Due to atmospheric phenomena such as rain and car washing, moisture inevitably enters the fuel tank and fuel lines. Excessive gum can cause premature failure of the fuel filter and clogging of fuel injectors, while moisture can lead to premature wear of the fuel pump and rusting of metal components in the fuel lines; 3. Different types and qualities of gasoline can result in varying degrees of gum and moisture accumulation. For example, gasoline in China is currently divided into three categories: unleaded gasoline, ethanol gasoline, and methanol gasoline. Unleaded gasoline is further classified into three types: National IV, National III, and National II. Unleaded gasoline produces more gum than ethanol and methanol gasoline, while ethanol and methanol gasoline are more prone to absorbing moisture.

What Type of Vehicle is the BMW i3?

The BMW i3 is a pure electric vehicle, classified as a sedan rather than an SUV. Here are more details about the BMW i3: 1. The BMW i3 measures 4006×1775×1600mm in length, width, and height, delivering a peak output of 125kW (170PS) and 250N·m, with a top speed of 150km/h and a 0-100km/h acceleration time of 7.3 seconds. 2. In terms of range, the daily driving distance remains unchanged at 200km. The new model introduces the more powerful BMW i3s, which boasts enhanced power output of 135kW (184PS) and 270N·m, equipped with a specially developed sports suspension. The 0-100km/h acceleration time is reduced to 6.9 seconds, with the same top speed of 150km/h and daily driving distance of 200km. 3. Additionally, both the i3 and i3s offer an optional range-extender version. The range-extender version is equipped with a 0.647L two-cylinder gasoline engine, maintaining the same power output. The curb weight increases from 1298kg (base i3) to 1430kg, with unchanged acceleration times. The daily driving range extends to 330km, with a maximum range of 396km. Under the NEDC cycle, the i3 range-extender version consumes 11.5-11.9kWh of electricity and 0.6L of gasoline per 100km. The average fuel consumption for the hybrid version is around 3.2 liters, making it very fuel-efficient. 4. Inside the cabin, the new BMW i3 continues to feature a carbon fiber-reinforced plastic (CFRP) passenger cell, offering various seat material options including leather and fabric. The new vehicle adheres to sustainable and eco-friendly principles, incorporating a significant amount of renewable materials. 5.

What is the method for replacing the clutch on a Pajero?

The method for replacing the clutch on a Pajero is as follows: 1. When removing or installing the clutch cover, use a special tool to secure the flywheel and make alignment marks. Tighten the bolts in stages during installation. 2. Insert a special tool or the transmission input shaft into the central spline hub and the transmission input shaft guide bearing to prevent the clutch disc from falling. During installation, also use a special tool or the transmission input shaft to align the driven disc with the transmission shaft guide bearing. 3. Before installing the new driven disc, fit it onto the transmission input shaft to check if the spline engagement is proper. Loosen the clutch cover bolts gradually in a diagonal pattern; tighten them in the same manner during installation. 4. When installing the driven disc, ensure the torsional damper faces backward and apply a small amount of grease to the spline hub. If there is any oil or grease on the clutch surface or pressure plate, wipe it off with a dry cloth before installing the clutch cover assembly. 5. Align the positioning pins on the clutch cover assembly with those on the flywheel, then gradually tighten the bolts alternately. Check for oil leaks from the engine's rear main bearing oil seal and the transmission's front oil seal. Repair any leaks if found. 6. The release bearing and transmission guide bearing do not require additional lubrication. Adding extra oil may cause oil contamination on the clutch driven disc, leading to clutch slippage. 7. During assembly, apply grease to the clutch driven disc spline hub, the front edge of the release bearing, the inner race of the release bearing, the release fork, and the contact points of the push rod.
