The latest range of Euro-3 engines from Caterpillar comprises two models coming five ratings with a dual-fuel version.
The 72-litre 3126E comes with ratings of 281) and 305hp; its HUE! system is carried over from the Euro-2 version. Indeed, Caterpillar's European engine boss, Luc Richard, says this technology will see the company through to Euro-4 in 2005, when European and US emissions standards will effectively coincide.
As part of its ACERT (Advanced Combustion Emissions Reduction Technology) initiative, Cat has shelved EGA as being complex, costly and unnecessary. On the 3126E the emission reductions have been achieved by simply retarding the injection timing and revising the engine management software.
The 255hp dual-fuel engine is aimed at operators In environmentally sensitive locations. It's based on the 3128E and uses electronically controlled multi-point injection to provide up to 85% of the engine's fuelling requirements with either LNG or CHG. Diesel is used to start up and Is continuously Injected to initiate the combustion process—if the gas tanks run dry the engine will run just as well on 100% diesel.
For now the 1112 features new electronics, with a higher capacity engine control module providing more computing power for more accurate fuel control. Other electronic changes include redundant (or back-up) sensors for improved reliability.
