HPCR systems produce twice as much injection pressure as mechanical fuel injection. Higher pressures mean finer fuel spray in the cylinder. Finer fuel spray means improved combustion and, ultimately, more power.
Injector tips are designed to handle the higher pressures in HPCR systems. However, diesel fuel is not. Consistently clean diesel is especially important in HPCR systems due to tight tolerances in the injection system. But, diesel fuel quality is notoriously inconsistent and therefore a threat to HPCR systems.
Diesel Engine Cutaway
Reports of problems with HPCR systems began in 2008. Poor engine operation was observed, with symptoms including poor drivability, rough running, and inability to cold start engines.1 Without proper maintenance in HPCR systems, engine damage is certain.
BG Solution: Clean to prevent engine damage
Poured in the fuel tank, BG 245 Premium Diesel Fuel System Cleaner is carried by the fuel through the injection system. BG 245 removes and dissolves deposits from the entire diesel injection system, including fuel injectors and combustion chambers. It is especially effective in removing heavy deposits in the injectors of HPCR systems. Plus, BG 245 contains a fuel lubricity agent to protect components from wear and cetane improver for cold starts.
BG 245:
- Restores injector efficiency
- Restores fuel flow through the rail
- Restores fuel efficiency
- Improves cold start
- Lowers harmful emissions
- Smoothes idle
