Abstract
An internal combustion engine and a method of controlling an internal combustion engine are provided, that are more efficient than existing engines. The internal combustion engine includes a combustion chamber, and the engine is configurable to operate in: a compressionless operating mode where the engine is driven by combustion of fuel and oxidant in the combustion chamber without compression of the fuel and oxidant; and a compression generating operating mode where the engine is used to compress fluid in the combustion chamber.
Claims20
An internal combustion engine comprising a combustion chamber, wherein the engine is configurable to operate in:
- a compressionless operating mode where the engine is at least partly driven by combustion of fuel and oxidant in the combustion chamber without compression of the fuel and the oxidant by a compression stroke of the engine without using any piston to compress the fuel and the oxidant, wherein the oxidant is at least one of air or oxygen;
- and
- a compression generating operating mode where the engine is at least partly used to compress a fluid in the combustion chamber using at least one piston to compress the fluid, wherein the fluid includes at least one of air or steam, and discharge the fluid that has been compressed without any fuel in the combustion chamber.
A method of operating an internal combustion engine comprising a combustion chamber, the method comprising:
- configuring the engine to operate in a compressionless operating mode where the engine is driven by combustion of fuel and oxidant in the combustion chamber without compression of the fuel and oxidant by a compression stroke of the engine without using any piston to compress the fuel and the oxidant;
- and
- subsequently reconfiguring the engine to operate in a compression generating operating mode where the engine is used to compress a fluid in the combustion chamber using at least one piston to compress the fluid, wherein the fluid includes at least one of air or steam, and discharging the fluid that has been compressed without any fuel in the combustion chamber.
