摘要

Invention Patent: B '' LOAD CONDITIONING SYSTEM TO ENABLE COLD START UP AND OPERATION OF PISTON TYPE ENGINES OPERATED BY DIESEL FUEL, WITH SPARK IGNITION '' D. B BACKGROUND OF THE INVENTION D. Internal combustion engine, operated by diesel fuel, piston type, with spark ignition, is equipped with a load conditioning system, which includes a fuel preheater to vaporize liquid fuel to allow the engine to start and at least one secondary heater to add additional heat to the load supplied to the engine. The fuel vaporizer receives liquid fuel from the engine's starting fuel circuit and uses a heater device, electrically or chemically powered, or a direct combustion heater. The secondary heater may be associated with the engine's charge inlet duct or the engine's combustion chamber. The secondary heater device can be activated electrically or chemically, or it can constitute a heat regenerator that retains heat from a previous combustion cycle of the engine. Fouling on the spark plug is prevented by using secondary chambers adjacent to the engine combustion chamber that direct high-speed gas expansion jets to the spark plug electrodes at each combustion cycle, during the power supply stroke. piston. first heating device
