Optimum Fuel Consumption Analysis in Machinery Operation

Study Notes

Optimum fuel consumption levels were found for a dozer operating continuously for different durations: 40 min (14.57 Lit), 45 min (16.34 Lit), 50 min (18.21 Lit), 55 min (20.03 Lit), and 60 min (21.92 Lit).
A combined graph showed that the optimum point for fuel consumption between 49-51 Lit was consistent across different working durations.
Diesel reconciliation by the CPWD method was conducted for each optimum case, with positive values indicating payments to the contractor.
Real-time data collection from a site involved a dozer with specific features like an operating weight of 22 tons, engine power of 164 kW, and fuel capacity of 107 gallons.
Theoretically, the fuel consumption per hour was calculated to be 25 Lit, while on-site consumption was observed to be 21.92 Lit for an hour of work.
Reconciliation by CPWD method for a 60-minute working duration showed a discrepancy between theoretical and actual site conditions, with the theoretical value being lower.
The conclusion highlighted the optimal fuel consumption levels for each working duration, the positive values in the CPWD reconciliation indicating payments, and the discrepancy between theoretical and real site conditions in fuel consumption.
References were provided for further reading on dozer workability estimation, fuel consumption trends in construction projects, and fuel consumption optimization models for heavy construction equipment.
