Abstract
An engine control unit of a multi-fuel is provided. The engine consumes a mixture of a first fuel and a second fuel. The engine control unit includes hardware circuitry that includes one or more processors configured to calculate an autoignition delay of the mixture of the air and the second fuel based on current operating conditions of the multi-fuel engine. The one or more processors also are configured to calculate an upper limit on an amount of the second fuel that is supplied to the multi-fuel engine based on the autoignition delay that is calculated.
Claims20
An engine control unit of a multi-fuel engine that consumes a mixture of a first fuel and a second fuel, the engine control unit comprising:
- hardware circuitry that includes one or more processors configured to calculate an autoignition delay of the mixture of the first fuel and the second fuel based on current operating conditions of the multi-fuel engine,
- the one or more processors also configured to calculate an upper limit on an amount of the second fuel that is supplied to the multi-fuel engine based on the autoignition delay that is calculated.
A method comprising:
- calculating an autoignition delay of a mixture of a first fuel and a second fuel that are supplied to a multi-fuel engine, the autoignition delay calculated based on current operating conditions of the multi-fuel engine;
- and
- calculating an upper limit on an amount of the second fuel that is supplied to the multi-fuel engine based on the autoignition delay that is calculated.
A method comprising:
- monitoring one or more operating conditions of a multi-fuel engine that consumes a mixture of air, a non-premixed fuel, and a premixed fuel;
- determining an amount of the premixed fuel that is supplied to the multi-fuel engine;
- calculating an autoignition delay of the mixture of the air and the premixed fuel, the autoignition delay representing a period of time before the premixed fuel ignites during knocking of the engine;
- and
- modifying operation of the engine based on the autoignition delay that is calculated.
