An electronic fuel injection (EFI) motorcycle is a new type of motorcycle that uses a microcomputer to control the fuel injector to supply fuel to the working cylinders based on the engine load, while cutting off fuel supply to non-working cylinders. Differences from conventional motorcycles: Compared with traditional carburetor motorcycles, EFI motorcycles are more fuel-efficient. An EFI motorcycle can save over 20% more fuel than its carburetor counterpart of the same model. With digital ignition and fuel injection functions, EFI motorcycles reduce fuel consumption and improve emissions, making them more environmentally friendly than carburetor models. They directly meet the Euro 11 emission standards and also feature easy starting. Working principle: EFI motorcycles adopt electronic fuel injection technology, replacing the carburetor with an EFI system. A microcomputer (ECU) equipped with specialized EFI software performs real-time intelligent control over fuel supply and ignition. The fuel supply is extremely precise, allowing the air-fuel ratio and ignition timing to always reach optimal levels under any operating condition or environment. As a result, EFI motorcycles achieve reduced fuel consumption, improved emissions, and significantly enhanced overall performance.

How Often Should Blue Shell Engine Oil Be Changed?

Blue Shell engine oil should be changed every 7,500 kilometers or 7-8 months. As a semi-synthetic oil, Blue Shell helps maintain engine cleanliness and reduces carbon buildup. The final oil change interval should be determined based on actual conditions such as vehicle condition, road conditions, and personal driving habits. Methods to determine if Blue Shell engine oil needs changing are as follows: Observe the oil color: If the oil color turns black or noticeable impurities float on the surface, it indicates the oil needs replacement. Monitor vehicle feel: If noticeable engine vibration occurs and the engine noise increases, it's time to change the oil. Oil test paper method: First, pull out the dipstick near the engine, take a small amount of oil, and drip it onto the oil test paper. Let it sit overnight until the oil fully diffuses on the paper. Observe the deposit ring, oil ring, and diffusion ring on the paper. If any of the following three conditions occur, the oil needs replacement. Distinct boundaries between the three rings: Can be used for a while but should be replaced soon. Oil ring disappears: Only the deposit ring and diffusion ring remain. Go to a repair shop or change it manually. Only a dark deposit ring remains: Replace immediately to avoid engine damage.

What causes the shaking when the vehicle is first started?

Shaking when the vehicle is first started is a normal phenomenon, and almost all cars experience some shaking when the engine is started. During engine startup, the engine operates unevenly, resulting in some shaking, which typically stops once the engine is running. Most cars use inline four-cylinder engines, which may also exhibit slight shaking after startup. If the engine shaking becomes more pronounced, it could indicate an issue with the engine mounts. Engine mounts, made of rubber, are located where the engine connects to the frame. These mounts help prevent the vibrations from the engine from being directly transmitted to the vehicle body.
