SYSTEMS AND METHODS FOR CETANE NUMBER RATING WITH ELECTRONIC FUEL INJECTION

An electronic fuel injection system for a cetane number rating system includes a fuel reservoir, a supply line, a drain line, an electrically-controlled fuel valve configured to selectively provide or inhibit fluid communication between the fuel reservoir and the supply line, an electrically-controlled drain valve configured to selectively provide or inhibit fluid communication between the fuel reservoir and the drain line, a low-pressure pump in fluid communication with the supply line, a high-pressure pump in fluid communication with an outlet of the low-pressure pump, and an electronic fuel injector in fluid communication with an outlet of the high-pressure pump. The high-pressure pump is configured to supply pressurized fuel from the fuel reservoir to the electronic fuel injector at a constant flow rate.
