AMERICAN BOSCH Product Lines We Repair
Our engineers are trained on the full AMERICAN BOSCH product range. Below are the major product families we service.
Fuel Injection Control Units (FICU)
Electronic fuel injection governors and control modules used in stationary engines and power generation sets. Common faults include solenoid valve stiction, pressure sensor drift, and fuel metering calibration loss affecting engine stability and fuel consumption.
Magneto Ignition Systems
High-voltage magneto and electronic ignition modules for industrial engines. Repair focuses on coil winding breakdown, breaker point erosion, capacitor degradation, and high-tension spark distribution failures that cause misfiring and engine shutdown.
Engine Governing Systems
Mechanical and electronic speed governors that maintain constant RPM under variable load conditions. Common issues include governor hunting oscillation, load droop calibration drift, and actuator arm linkage wear affecting engine speed stability.
Fuel Pump Drive Controllers
Electronic controllers for fuel supply pump operation in large stationary engines. Faults include pump driver transistor burnout, fuel supply pressure loss, and fuel cutoff relay failure during engine operation.
Injection Timing Modules
Precision timing control electronics for fuel injection advance and retard in diesel and dual-fuel engines. Degradation causes late injection, poor combustion efficiency, excessive exhaust smoke, and reduced power output.

Common AMERICAN BOSCH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMERICAN BOSCH equipment arriving at our workshop.
- ✓Fuel injection solenoid valve stiction and erratic metering — American Bosch injection solenoids suffer carbon buildup and varnish formation in the valve seat when fuel quality is poor or equipment sits unused. This restricts valve movement and creates fuel flow oscillation, causing engine hunting and rough idle.
- ✓Governor hunting oscillation and unstable engine speed — American Bosch electronic governors develop hunting when feedback potentiometer signal noise increases, capacitor filters age, or load-sensing transducers drift. Mechanical linkage wear in the governor actuator arm also reduces damping and causes hunting.
- ✓High-voltage magneto coil breakdown and intermittent spark loss — American Bosch magneto primary and secondary windings degrade from moisture ingress, thermal cycling, and mechanical vibration in industrial engine installations. Aged insulation allows high-voltage tracking and corona discharge, causing intermittent misfiring.
- ✓Fuel pump drive transistor burnout and fuel starvation — American Bosch fuel pump drive circuits use older discrete transistor designs susceptible to thermal runaway when supply voltage spikes occur. Inductive kickback from solenoid pump drives causes transistor junction failure, cutting fuel supply and stalling the engine.
- ✓Injection timing advance/retard module signal loss and erratic timing — American Bosch dual-fuel timing processors fail when crank angle sensor signals degrade from sensor gap drift, damaged sensor wiring, or loss of magnetic shielding. Signal noise causes the timing module to issue incorrect advance commands, degrading combustion efficiency.
- ✓Electronic governor pressure transducer drift and load regulation failure — American Bosch pressure transducers in fuel injection governors become unstable when ceramic sensing elements degrade from thermal shock, or amplifier IC offset voltage drifts. This causes the governor to lose load-sharing accuracy, resulting in engine cycling and overload trips.

Frequently Asked Questions — AMERICAN BOSCH Repairs
Do you repair American Bosch equipment anywhere in India?+
Yes. Synchronics repairs the full American Bosch product range across India — fuel injection governors, magneto systems, fuel pump controllers, and injection timing modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other industrial cities. Same-facility turnaround in our Vadodara, Gujarat laboratory.
What is the typical turnaround time for American Bosch fuel injection governor repair?+
Standard American Bosch electronic governor repair takes 7-10 working days from receipt at our Vadodara facility. This includes complete diagnostics, component testing, solenoid valve cleaning, transducer recalibration, and full-load bench testing. Emergency express service is available for critical power plants and genset installations — contact our service team for same-day assessment.
Can Synchronics repair American Bosch magneto systems for old industrial diesel engines still running in Indian mills?+
Absolutely. Many Indian sugar mills, cement plants, and textile mills still operate vintage American Bosch magneto-equipped stationary diesel engines. Our engineers have deep expertise rewinding magneto coils, replacing aged capacitors and breaker points, and balancing rotor assemblies. We perform insulation testing to ensure magneto reliability and prevent unexpected engine shutdowns during critical production runs.
What causes American Bosch injection timing modules to fail, and how do you diagnose the fault?+
American Bosch dual-fuel and diesel timing modules fail primarily from crank angle sensor signal degradation, supply voltage noise, or aged signal conditioning capacitors. Synchronics uses precision oscilloscope tracing to capture sensor signals and timing module response curves. We test the module under simulated engine load using our advanced test bench, then validate timing accuracy across the full RPM and load range before returning the unit.
Do you stock American Bosch replacement components, or do you repair existing units in-house?+
Synchronics primarily performs component-level repair and remanufacturing of American Bosch equipment — we rebuild fuel injection solenoids, rewind magneto coils, recalibrate governors, and restore electronics to OEM specifications. For obsolete or severely damaged assemblies where repair is uneconomical, we can advise on sourcing replacement modules or guiding customers through retrofitting with modern control systems suitable for Indian industrial applications.
How do I send my AMERICAN BOSCH unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AMERICAN BOSCH drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AMERICAN BOSCH repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AMERICAN BOSCH unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
