Spark plugs can only ignite the fuel at one end of the chamber. A laser ignites the fuel in the middle of the chamber instead, burning more of the fuel and improving combustion efficiency by 27 per ...

The pollutant emissions and high-energy consumption of combustion engines using conventional spark plugs have long been serious environmental problems. Now, it has been demonstrated that lasers can ...

Generally, homogeneous mixture combustion is preferred at high loads in conventional spark-ignition engines. But homogeneous mixture combustion can lead to high hydrocarbon (HC) emissions at low loads ...
