Question

Piston crevice volume is one of the reasons for ___________ emission:

• A. Unburned hydrocarbon
• B. Carbon mono oxide
• C. Oxides of nitrogen
• D. Particulate matter

Hint:

Understanding engine design can help identify how modifications might reduce harmful emissions and improve efficiency.
