Solves poor fuel atomization, incomplete combustion, black smoke, and low torque in urban driving. Improves scavenging efficiency and restores power for NPR trucks.
Product Design Philosophy
Beveled crown optimizes combustion swirl and improves scavenging efficiency. Designed for 4HF1 engines in NPR trucks, balancing fuel economy and durability in urban delivery cycles.
How it works
Beveled crown guides incoming air into a swirling motion, mixing thoroughly with injected fuel for complete combustion. Reciprocates to convert heat energy into mechanical power.
