Abstract
A 2-cycle, direct-injection diesel engine configured to accommodate low cetane diesel and jet fuels. The engine includes combustion chambers having surfaces which are operable at high temperatures during engine operation to increase the combustion rate of low cetane fuels. The engine is further configured to reduce starting times in cold and/or low pressure situations such as those experienced during attempts to restart a plane engine at relatively high altitudes.
Claims20
An engine, comprising:
- a piston;
- an engine block assembly with a cylinder having a sleeve within which the piston is located, an intake port, and an exhaust port;
- a head assembly coupled to the engine block assembly;
- and
- a fireplate fixed between the sleeve and the head assembly.
2 more elements
An engine, comprising:
- an engine block having a cylinder with an intake port and an exhaust port;
- a fluid flow channel that cools the engine block and is located within the engine block adjacent to one of the intake port and the exhaust port;
- a head assembly including a fuel flow channel to cool the head assembly;
- a fuel reservoir coupled to the fuel flow channel;
- a fuel injector assembly coupled to the fuel flow channel on the head assembly, to transport a fuel to an injector tip in the intake port and return excess fuel from the injector tip to a fuel reservoir;
- and
- a piston positioned to oscillates within the cylinder.
4 more elements
An engine, comprising:
- an engine block having four or more cylinders, each cylinder has an intake port and an exhaust port;
- a fluid flow channel located adjacent to one of the cylinders within the engine block adjacent to one of the intake port and the exhaust port that cools the engine block;
- a sleeve fixed within each cylinder of the engine block;
- a head assembly having a fuel flow channel to supply fuel to each cylinder, the fuel flow channel supplies fuel to the intake port of the cylinder such that the fuel cools the head assembly;
- a fuel injector assembly coupled to the fuel flow channel on the head assembly, the fuel injector assembly transports a fuel to an injector tip in each cylinder and returns excess fuel from the injector tip to a fuel source;
- a fireplate located between the sleeve on each cylinder and the head assembly;
- and
- a piston within the sleeve of each cylinder, the piston configured to oscillate within the sleeve.
