Therefore, it can be effectively realized to improve the working efficiency of the engine by modifying parts, or to improve the burning efficiency of fuel while simultaneously saving fuel and increasing horsepower. But the most important or "heat dissipation" the core of the matter itself to good quality, that is more efficient.

The 400 horsepower exploded by the 2.5T inline five-cylinder engine is seriously inconsistent with its compact body. Coupled with the easy handling characteristics brought by the short wheelbase, this kind of power is surging, and the feeling of where to hit is fascinating.

The role of the exhaust valve is to exhaust the exhaust gas after combustion and dissipate heat. The role of the intake valve is to draw air into the engine and mix it with fuel for combustion.

The air valve is connected to the air filter, and the exhaust valve is connected to the exhaust tube. In general, the intake valve of the used engine is cleaner than the exhaust valve. The door moves upward to open the exhaust valve, the spark plug opens the exhaust valve after ignition, and the intake valve opens before the ignition.

The engine exhaust valve mechanism directly determines the performance of the engine, and the exhaust valve in the entire exhaust valve mechanism is a vital component, so when the exhaust valve clearance changes, the engine performance will be biased.

The role of the valve is to be responsible for inputting air into the engine and exhausting the exhaust gas after combustion. From the engine structure, it is divided into intake valve and exhaust valve. The role of the intake valve is to draw air into the engine and mix it with fuel for combustion; the role of the exhaust valve is to exhaust the exhaust gas after combustion and dissipate heat.

When the engine is operating, the valve will expand as the temperature rises. If there is no gap between the valve and its transmission parts in the cold state or the gap is too small, then in the hot state, the heated expansion of the valve and its transmission parts will inevitably cause the valve to close tightly, causing the engine to leak during the compression stroke and the power stroke Gas, so that the power drops, even in severe cases, it is not easy to start. In order to eliminate this phenomenon, when the engine is coldly assembled, a certain gap is left in the valve and its transmission mechanism to compensate for the expansion of the valve after heating. This gap is called the valve gap.
