Benchmarking a 2016 Honda Civic 1.5-liter L15B7 Turbocharged Engine and Evaluating the Future Efficiency Potential of Turbocharged Engines
As part of the U.S. Environmental Protection Agency’s continuing assessment of advanced light-duty automotive technologies to support the setting of appropriate national greenhouse gas standards, and to evaluate the impact of new technologies on in-use emissions, a 2016 Honda Civic with a 4-cylinder 1.5-liter engine and continuously variable transmission (CVT) was benchmarked. The test method involves installing the engine and its CVT in an engine dynamometer test cell with the engine wiring harness tethered to its vehicle parked outside the test cell. Engine and transmission torque, fuel flow, tailpipe emissions, in-cylinder pressure, key engine temperatures and pressures, and OBD/epid CAN bus data were recorded. The paper documents test results with EPA Tier 2 and Tier 3 test fuels for idle, low, medium and high load engine operation, as well as motoring torque, wide-open throttle torque, and fuel consumption during transient operation.
