The 4-cylinder engine is also the most common type of engine in daily life, and the arrangement of this engine is mostly "L" shaped. 2. In addition to the 4-cylinder engine, there are also 3-cylinder, 6-cylinder, 8-cylinder, 10-cylinder and 12-cylinder engines. The more cylinders the engine has, the greater its output power. 3. Currently, people are not very accepting of three-cylinder engines, which stems from the disadvantages of three-cylinder engines. As the usage time increases, the vibration of the engine may become increasingly severe. 4. The engine model equipped in Haval H4 is GW4G15F, which is an engine independently developed by Haval. The cylinder head and block of this engine are made of aluminum alloy. 5. The maximum output power of the 1.5T version engine is 110 kW, the maximum torque is 210 N·m, the 0-100 km/h acceleration time is 10.47 seconds, and the comprehensive fuel consumption per 100 km announced by the Ministry of Industry and Information Technology is 6.8L.

Is Semi-Clutch Start Unnecessary on Flat Roads?

Not using the semi-clutch state will definitely cause stalling due to sudden power surge. Here are the consequences of fully releasing the clutch pedal immediately: Immediate stall: If the engine RPM is insufficient with inadequate torque, the engine will stall instantly. Accident risk: If both engine RPM and torque are sufficiently high, the vehicle will lurch forward abruptly, causing impact on transmission gears and high accident probability. Starting technique: Keep semi-clutch duration brief to prolong clutch plate lifespan. Specifically for flat-road starts: depress clutch - engage gear - release handbrake - slowly lift clutch to semi-clutch state while gently applying throttle - when reaching proper 1st-gear coasting speed, fully release clutch immediately.

Do All Four Ignition Coils Need to Be Replaced Together?

Whether to replace all four ignition coils depends on their specific usage conditions. If only one or two ignition coils have failed while the others remain unaffected and are still in good condition with a lifespan under 100,000 kilometers, you can simply replace the faulty ones without needing to replace all four. However, if the ignition coils have been in use for a while and their lifespan exceeds 100,000 kilometers, it is advisable to replace all of them even if only one has failed. Ignition Coil Replacement Procedure: 1. Open the engine hood and remove the engine cover if present, exposing the ignition coils for each cylinder. 2. Slowly lift the yellow plug outward, being careful not to break it. Then press down on the black latch handle while gently pulling the plug outward. Since each plug corresponds to a specific cylinder, ensure they are not mixed up. 3. Use the appropriate socket tool to remove the fixing screws for each ignition coil and pull out the coils. 4. Insert the new ignition coils into the coil holes, ensuring they are securely connected to the spark plug ends. 5. Secure the ignition coils with the fixing bolts and plug in the corresponding coil connectors for each cylinder, pushing the plug locks inward to the locked position. 6. After installation, test whether the ignition coils are functioning properly. If everything is normal, reattach the engine cover to complete the process.

Can You Turn Right on a Straight Red Light?

A straight red light does not allow a right turn. A full green light in principle permits left turns, going straight, and right turns. A green arrow light allows movement in the specified lane according to the direction of the arrow, and arrow traffic lights are usually accompanied by lane indicator signs. When vehicles pass through an intersection with arrow traffic lights, in addition to following the guidance of the arrow lights, they must also choose the correct lane. When the left-turn green arrow light is on, vehicles can only pass through the left-turn lane. When the straight green arrow light is on, vehicles can only pass through the straight lane. In the absence of additional traffic signs or markings, a right turn can be made under the premise of ensuring safety. If there is a sign indicating to proceed straight on a right turn when the straight light is green, then the green straight light allows passage. At any time, pedestrians on crosswalks must be given way. Modern traffic signals are very user-friendly, and at particularly complex intersections, there may be traffic police directing traffic or Chinese character prompts. Road traffic signals are a category of traffic safety products. They are an important tool for strengthening road traffic management, reducing the occurrence of traffic accidents, improving road usage efficiency, and enhancing traffic conditions. They are applicable at intersections such as crossroads and T-junctions, controlled by road traffic signal controllers, guiding vehicles and pedestrians to pass safely and orderly.

Should the internal circulation be turned on when AC is on?

After turning on the AC, if cooling is required, the internal circulation must be activated; otherwise, it would be ineffective. Below is an introduction to internal circulation: Function introduction: Internal circulation is a state of the car's air conditioning system. In this state, the air exchange channels between the inside and outside of the car are closed. When the fan is off, the air inside the car does not circulate; when the fan is on, the air drawn in comes only from inside the car, forming an internal air circulation. Principle: Car air conditioning systems generally have an electric or manual internal/external circulation switch. When external circulation is used, the air conditioning draws air from outside the car, while internal circulation reuses the air inside the car.
