Particulate emissions are created through the burning of diesel fuel in an engine and are seen as the black smoke emitted when load is applied to a diesel engine. These particulates can cause a variety of health effects, the biggest one being cancer. To reduce the amount of particulates being produced less fuel needs to be burned or combustion needs to happen more efficiently. In order to do this, methane injection has been incorporated into the test diesel engine so that it burns a mixture of both fuels. Methane burns cleaner therefore has less particulate emissions and costs much less to produce than diesel. However, diesel must be kept for idle states and to produce more torque Previous research suggests that a decrease in emissions will come with a cost to power because methane produces less power per weight. Baseline tests were performed to record particulate emissions, fuel economy, and engine power. This was done on a stock engine and with diesel fuel only; no methane was added at this time. Methane is then added in increments to record the effects on each of the previously mentioned categories. A decrease in particulate emissions with an increase in fuel economy and engine power is what the desired data would look like. Currently the research is incomplete and needs further testing to finalize the results. Conclusive data will be obtained in the next few months that may confirm previous research.
