Throughout emissions cycle load points, the OP4 demonstrated 0.4 Background.
The measure is targeted at reducing tampering with the emissions control systems, which can result in higher emissions. ARB estimates that motorcycles produce up to 15 times the emissions per mile as the average new car or light-duty truck. g/km HC+NO x , compared to the 2004 Tier I standard of 1.4 Background.
Key changes to implement the integrated cycle are isothermal compression and heat addition from the exhaust gas to the charge air after the end of compression. To transfer exhaust gas heat at the end of compression requires the use of a “split cycle” in which the standard four-stroke sequence is split into two separate elements.
The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaustemissions with conventional, low-cost aftertreatment. Injection patterns can also be extensively optimized to tune performance and emissions for the fuels and applications of interest. Earlier post.).
