EQUIPMENT AND PROCESS FOR ELECTRONICALLY CONTROLLED INJECTION OF LIQUIFIED AND COMPRESSED GAS IN DIESEL ENGINES

摘要

The invention relates to apparatus and method for the electronically controlled feeding of liquid or compressed gas into diesel engines (40) for dual diesel oil-and-gas fuelled vehicles, which can be retrofitted in vehicles and comprises a gas container (48) and a gas feeding valve, a feeder valve and a pressure reduction unit (35) in the high pressure gas circuit and respectively an electronic control unit for regulating the feeding of gas volume in the low pressure gas circuit. The invention is characterized in that there is a sampling stub (47) installed in the air intake (41) of the diesel engine (40), which is connected through pipes (44, 43) partly with the pressure reduction unit (35), and partly with the comparator unit (28) which compares and evaluates the pressure in the air intake (41) and the gas injection valve (30).
