It is important to keep in mind while diagnosing engine concerns that the fundamentals of engine operation (correct mixture of air and fuel sufficiently compressed and ignited at the proper time) are not different. The following is an overview of these systems.Basic Air Đào tạo sửa chữa ô tô: Technical training Induction SystemThe amount of air is measured and the air is controlled for efficient engine operation.

The air intake chamber and intake manifold are tuned for efficient engine operation.There are many variations on the basic air induction system.
