There are many ways to classify CNG Injection Kits , and they can be classified in different ways.

According to the continuity of injection, the gasoline injection system is divided into continuous injection and intermittent injection. Continuous injection means that during engine operation, the injector continuously injects into the intake port, and most of the gasoline is injected when the intake valve is closed. This type of injection is mostly used in mechanically controlled or electromechanical hybrid controlled gasoline injection systems. Intermittent injection means that gasoline is intermittently injected into the intake port during engine operation. Electronically controlled gasoline injection systems all adopt intermittent injection methods.

According to the different injection parts, it can be divided into two types: in-cylinder injection and out-cylinder injection. So there are many ways to classify them in different ways. The classification of CNG Conversion Kits is the same, and the classification is different in different ways.
