Abstract
Disclosed is a piston ported two-stroke compression ignition internal combustion engine comprising: a cylinder having a fixed closed end, and a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween; at least one heater to heat the combustion chamber; and a controller to control the heater to heat the combustion chamber when the controller determines that a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder.
Claims17
A piston ported two-stroke compression ignition internal combustion engine comprising:
- a cylinder having a fixed closed end, and a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween;
- at least one heater to heat the combustion chamber;
- and
- a controller to control the heater to heat the combustion chamber when the controller determines that a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder.
A piston ported two-stroke compression ignition internal combustion engine comprising:
- a cylinder having a fixed closed end, and a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween;
- at least one heater mount for holding a heater to heat the combustion chamber;
- and
- a controller to control the heater, when the heater is held by the heater mount, to heat the combustion chamber when the controller determines that a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder.
A non-transitory machine-readable storage medium storing instructions that, when executed by a controller of a piston ported two-stroke compression ignition internal combustion engine, the engine comprising a cylinder having a fixed closed end, a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween, and at least one heater to heat the combustion chamber;
- and the controller to control the heater to heat the combustion chamber, cause the controller to:
- determine whether a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder;
- and
- control the heater to heat the combustion chamber when the controller determines that the temperature of the combustion chamber has fallen below the threshold temperature during reciprocation of the piston within the cylinder.
An engine control unit comprising a non-transitory machine-readable storage medium, the non-transitory machine-readable storage medium storing instructions that, when executed by a controller of a piston ported two-stroke compression ignition internal combustion engine, the engine comprising a cylinder having a fixed closed end, a piston for reciprocation within the cylinder, wherein the closed end of the cylinder and the piston together define a combustion chamber therebetween, and at least one heater to heat the combustion chamber;
- and the controller to control the heater to heat the combustion chamber, cause the controller to:
- determine whether a temperature of the combustion chamber has fallen below a threshold temperature during reciprocation of the piston within the cylinder;
- and
- control the heater to heat the combustion chamber when the controller determines that the temperature of the combustion chamber has fallen below the threshold temperature during reciprocation of the piston within the cylinder.
