IC motor has two separate fuel injection systems and a spinning air intake flow, to run on diesel when idling and under a low loading, with a second fuel of gasoline or a gas injected on full running speeds

摘要

The internal combustion vehicle motor has two separate direct fuel injection systems, using two fuels or combustible gases using diesel and gasoline or other fuels. While the motor is idling, diesel fuel is used alone until the motor speed reaches the lower loading range. Then, between the lower loading range and full power, gasoline or another fuel is used together with diesel. The air intake is formed into a strong spin flow (3) within the cylinder combustion zones (10) by the structure of the pistons (11) and the cylinders. The diesel is initially injected (1) into the swirling intake air flow to be burned and act as the ignition for the additional injected fuel (2). The diesel fuel does not have to be in a direct injection, while the second fuel is injected directly into the cylinders.
