deutz engine 912 1011 1012 and 1013 injection pump , Iran

Fuel injection pumps for DEUTZ 912, 1011, 1012, and 1013 engines are precision-engineered to deliver exact fuel volumes at high pressures up to 1800 bar. These pumps feature calibrated plunger and barrel assemblies, ensuring injection timing accuracy within ±0.5 degrees crank angle. Materials such as hardened alloy steel and wear-resistant coatings provide long-term durability under continuous operation. Flow rates are precisely matched to each engine model, ranging from 60 to 120 liters per hour depending on cylinder configuration. The pumps maintain stable performance at operating temperatures between -20°C and 95°C, and are designed to resist cavitation, vibration, and thermal expansion. Proper calibration and maintenance of the injection pump optimize combustion efficiency, reduce emissions, and extend engine life across DEUTZ 912, 1011, 1012, and 1013 series engines.

Each pump incorporates precise control mechanisms for fuel delivery, including mechanical governors or electronic actuators in advanced models. The pump’s sealing components are engineered to withstand pressures exceeding 1800 bar without leakage. Tolerances in the plunger bore, delivery valve, and timing gears are maintained within ±0.02 mm to ensure repeatable performance. These pumps support injection intervals of 2–6 milliseconds, enabling uniform fuel atomization and consistent power output. High-precision manufacturing, including CNC machining and surface finishing, reduces friction and wear while maintaining efficiency. By ensuring accurate fuel metering and timing, the DEUTZ injection pumps contribute to lower fuel consumption, reduced smoke, and enhanced engine reliability over 5000 operating hours under typical duty cycles.You can order and buy deutz engine 912 1011 1012 and 1013 injection pump from Iran by contacting us through whatsaap and email.

Signs of deutz engine fuel injection pump malfunction

Signs of fuel injection pump malfunction in DEUTZ diesel engines include reduced injection pressure, difficult engine starting, and black or blue smoke from the exhaust. RPM fluctuations exceeding ±150 rpm at idle, fuel leakage at pump connections, and unusual clicking or buzzing noises from the pump are also key indicators. Acceleration loss of 10–20% under medium load, fuel temperature rise up to 60°C at the pump inlet, and increased fuel consumption up to 5% can signal pump efficiency decline. These issues are often caused by plunger and barrel wear, clogged fuel filters, or faulty delivery valves, requiring precise inspection and timely maintenance.

Injection timing issues cause engine vibration and uneven combustion. Injection pressure drops over 100 bar below standard under medium load, output power reduction up to 15%, and emissions rising over twice normal levels are critical warning signs. Fuel flow fluctuations exceeding ±5% per operating cycle, fuel leakage inside the pump housing, and fuel discoloration are additional technical indicators of pump malfunction. Early detection using pressure gauges and digital diagnostic tools reduces repair costs and prolongs DEUTZ diesel engine life.
