- •
HCNG enhances idle stability, providing flexibility to control other parameters.
- •
Fuel economy and THC and CO emissions were improved in HCNG idle operations.
- •
Despite H2 addition, NOx is lower for HCNG than CNG owing to lower fuel supplied.
- •
NOx monotonously decreases as 位 increases, owing to less fuel in idle condition.
- •
Spark retardation and lean EAR improve HCNG cold-start performance in at idle.
