Abstract
Methods and systems are provided for adjusting a substitution ratio based on water in a combustion mixture of a multi-fuel engine. In one example, a method includes adjusting a substitution ratio in response to an amount of water provided to a multi-fuel engine configured to combust a first fuel and a second fuel, the second fuel different than the first fuel.
Claims12
A method, comprising:
- adjusting a substitution ratio in response to an amount of water provided to a multi-fuel engine configured to combust a first fuel and a second fuel, the second fuel different than the first fuel, wherein the first fuel is a liquid fuel and the second fuel is a gaseous fuel, and wherein the amount of water is based on an amount of condensate in an EGR cooler.
A method, comprising:
- adjusting a substitution ratio in response to an amount of water provided to a multi-fuel engine configured to combust a first fuel and a second fuel, the second fuel different than the first fuel, and further comprising adjusting a routing of EGR in response to an amount of water in the EGR.
A method, comprising:
- adjusting a substitution ratio of a cylinder in response to an amount of water provided to the cylinder, wherein the substitution ratio is based on two or more of diesel, hydrogen, ammonia, and ethanol being included in a combustion mixture;
- and
- adjusting the amount of water provided to the cylinder via adjusting a routing of EGR, wherein adjusting the routing of EGR comprises flowing EGR from a donor cylinder to decrease the amount of water provided to the cylinder.
A method, comprising:
- adjusting a substitution ratio of a cylinder in response to an amount of water provided to the cylinder, wherein the substitution ratio is based on two or more of diesel, hydrogen, ammonia, and ethanol being included in a combustion mixture;
- and
- adjusting the amount of water provided to the cylinder via adjusting a routing of EGR, wherein adjusting the routing of EGR comprises re-ingesting EGR via adjusting an exhaust valve timing to decrease the amount of water provided to the cylinder.
