The 4CR0197 diesel fuel injector is a heavy-duty HEUI fuel injector assembly engineered for erpillar 3126 series diesel engines, covering the 3126, 3126B, and 3126E engine platforms. In the HEUI system, high-pressure engine oil provides the hydraulic force for injection while the ECM electronically controls injection timing and fuel quantity. This architecture directly influences atomization quality, combustion stability, cold starting, fuel economy, emissions, and overall engine response, making injector condition critical to engine performance.
The 3126 family is a 7.2-liter inline six-cylinder four-stroke diesel engine with a 110 mm x 127 mm bore and stroke, and a complete engine normally uses six injectors. The 4CR0197 serves medium-duty trucks, buses, RVs, construction equipment, industrial power units, marine propulsion packages, and generator sets. Depending on stock, the injector can be supplied as new, original quality, remanufactured, rebuilt, or aftermarket replacement, serving diesel repair shops, distributors, fleet maintenance companies, and engine rebuilders.
The primary reference number is 4CR0197, also written as 4C-R0197 or 4CR-0197. Frequently associated 3126 injector numbers include 0R-9350, 10R-1267, 173-4059, and 156-8895, with additional family references such as 177-4754, 10R-0782, 222-5966, 232-1183, 2C0273, 198-4752, 174-7526, 188-1320, 10R-9237, and 10R-0781. Because 3126 engines vary by production year, emissions level, ECM software, and engine arrangement, all numbers must be verified by engine serial number and original injector marking before ordering.
