An engine (104) for use in a machine comprises an engine block (108). A cylinder head (106) is mounted to the engine block (108). A combustion chamber (126) is formed at least partially by the cylinder head (106). A piston (112) is slidably disposed in the...

Engine piston with a low heat transfer combustion chamber embedded therein, the piston defining, at least partially, an axial development (C), and having a top (S) wherein a combustion chamber (13) is embedded; the combustion chamber (13) having a half-ell...

The combustion engine has a cylinder and a piston (1). The piston has a combustion chamber recess (2) at upper side, and trough base (3) which is upwardly arched towards a center. An injection nozzle (4) generates fuel jet (6) whose center line (7) is exte...

In a compression stroke, fuel injection valve 2 injects a single portion of the fuel immediately after -28° ATDC. Immediately after this injection, a second portion of the fuel is injected as close as possible to the first injection without overlapping. T...

The regulating process for an engine running on two fuels (A, B) involves controlling the supply rate of the second fuel (B) so that the mixture pressure in the induction manifold is made to conform to a set mixture pressure value (P2'), depending on the s...

The nozzle (3) has injection holes distributed on its periphery in n vertical rows, where the number of holes of each row is selected according to a flow of the row. The flow and a position of each row with respect to a cavity (4) are selected according to...

The piston has a tulip (56) comprising a central combustion zone (60) and a peripheral combustion zone (62) surrounding the central combustion zone. An injection unit (44) includes an injector (58) for selectively injecting fuel towards both the (60, 62) z...

The method for the governing of an internal combustion engine entails feeding to the engine at least temporarily a first fuel (A) and a second fuel (B), whereby the amount of first fuel fed to the engine per time unit is controlled or kept constant dependi...
