Abstract
A method of controlling a reciprocating internal combustion engine comprising: a cylinder defining a cavity having a first end and a second end; and a piston moveable within the cavity of the cylinder between the first end and the second end, the method comprising: receiving at least a first signal; determining a quantity of liquid air to be injected using at least the received first signal; controlling injection of the determined quantity of liquid air into the first end of the cavity at a first time when the piston is closer to the first end than the second end.

A method of controlling a reciprocating internal combustion engine comprising:
- a cylinder defining a cavity having a first end and a second end;
- and a piston moveable within the cavity of the cylinder between the first end and the second end, the method comprising:
- receiving at least a first signal;
- determining a quantity of liquid air to be injected using at least the received first signal;
- controlling injection of the determined quantity of liquid air into the first end of the cavity at a first time when the piston is closer to the first end than the second end.
Apparatus for controlling a reciprocating internal combustion engine comprising:
- a cylinder defining a cavity having a first end and a second end;
- and a piston moveable within the cavity of the cylinder between the first end and the second end, the apparatus comprising a controller configured to:
- receive at least a first signal;
- determine a quantity of liquid air to be injected using at least the received first signal;
- and
- control injection of the determined quantity of liquid air into the first end of the cavity at a first time when the piston is closer to the first end than the second end.
