Fuel & Combustion Diagnosis

Diesel fuel, air and combustion faults — smoke diagnosis, fuel contamination, injection and the loading problems that damage engines without any component failing. Written for Kenyan conditions, where dust loading, altitude derating and long-stored fuel matter more than temperate assumptions allow.

What this covers

• ▪Smoke diagnosis — black, blue and white — Generator Excessive Smoke
• ▪Air restriction and turbocharger faults — Air Restriction and Turbocharger Faults
• ▪Wet stacking and light-load damage — Generator Excessive Smoke
• ▪Fuel contamination, water and filtration — Diesel Fuel Contamination
• ▪Injection and combustion faults — Generator Excessive Smoke
• ▪Altitude and ambient derating — Altitude and Ambient Derating
