Abstract: A method for starting a gaseous fuel internal combustion engine (10) is disclosed. According to the disclosed method, the engine is rotated using a start device until a first speed threshold is reached. After reaching the first speed threshold, pilot fuel is supplied to a plurality of cylinders (26A-26D) of the engine to combust the same. After performing an ignition health check, gaseous fuel is supplied to a relatively large number of cylinders (26A-26D) to start accelerating the engine up to a second speed threshold. After reaching said second speed threshold, the engine is operated with a lower number of cylinders until a rated speed of the engine is reached.

Abstract: Provided is a natural gas engine that is equipped with an exhaust gas introduction mechanism that introduces exhaust gas (G) into a cylinder during an intake stroke, and in which the amount of diesel fuel (f) injected into a cylinder is set to a diesel fuel amount for idling condition across the entire operating region of an engine, engine output is increased or decreased by increasing or decreasing the amount of a natural gas fuel (C), and fuel injection of the diesel fuel (f) into a cylinder is performed using multi-injection in a high load region in which the accelerator opening degree (±) is greater than a preset first opening degree (±1). As a result, natural gas fuel is ignited in a reliable and stable manner across the entire operating region and highly efficient combustion is performed using a small amount of fuel and a small amount of intake air in an engine that uses diesel fuel as an ignition source and natural gas fuel as a main fuel. In addition, knocking resulting from detonation is minimized even when the engine operation condition is in a high load region.

Abstract: A method of evaluating operability of gaseous fuel admission valves (58) of a dual fuel internal combustion engine (100) is disclosed that is performed, for example, during the transition from liquid to gaseous fuel. The method comprises operating (step 312) the dual fuel internal combustion engine (100) on liquid fuel; supplying (step 354) gaseous fuel to the gaseous fuel admission valves (58) at a pressure above an intake manifold air pressure thereby setting a differential gas pressure across the gaseous fuel admission valves (58); operating (step 356) the gaseous fuel admission valves (58) to add gaseous fuel to intake air while operating the dual fuel internal combustion engine (100) primarily on liquid fuel; measuring (step 360), for each cylinder of the plurality of cylinders a combustion process parameters such as the cylinder pressure; and evaluating (step 362) operability of the gaseous fuel admission valves (58) based on the measured combustion process parameters. Deviating gaseous fuel amounts may result in cylinder-specifically deviating combustion process parameters, allowing to identify malfunctioning gaseous fuel admission valves.

Abstract: A second plant (200) is associated to a Diesel cycle engine already provided with a first plant (100) for supply of high-pressure diesel to electro-injectors (9) of an engine (M). The second plant is able to supply commandably-ignited gaseous fuel to electrically-controlled gas injectors (85) opening in an aspirating manifold (C) of the cylinders of the engine (M). A device (10) is inserted in the seating originally destined to receive a glowplug, able to function both as a pre-heating glowplug and as an igniting sparkplug. A second control board (250) controls and manages the second plant (200) and imposes switching of the supply of the engine from diesel to gas or vice versa.
