The exhaust gas from the engine is directly led into the engine, which will ignite the gasoline next to the Phoenix Gate? Can it be as full as a three-way oil pan?

If the distance between the exhaust port and the intake throttle is too close and there is no fire extinguishing measure, the choke fuel may be ignited, which is why the tanker should install a fire extinguishing cap on the exhaust pipe.

The combustion mode you described seems to be able to burn more fully and make full use of fuel, but in fact, because the working mode of internal combustion engine is different from that of oil-fired boiler, exhaust gas will enter the working cycle again, causing great damage to the engine structure.

The most prominent problem is carbon deposition in the air inlet, as well as problems such as oil blockage, spark plug carbon deposition and piston carbon deposition.

In fact, many automobile engines are very advanced now, which can make full use of fuel and have high efficiency. Coupled with the continuous progress and introduction of turbine technology, the combustion efficiency has been excellent. Reusing the waste gas into the working cycle will do more harm than good, and the loss will outweigh the gain.

I hope the answer is what you want.
