Thanks to our excellent know-how in engine technology, and with more than 5 million engines manufactured - John Deere are the engine manufacturer of choice for a variety of industrial applications including: drilling equipment, rock crushers, forklifts, air compressors, generating sets, compactors, loaders and many others.
When John Deere began selecting technologies to meet Tier 3/Stage III A regulations, we did so with the understanding that different markets have different needs. Some customers required higher performance and improved fuel, economy, some just wanted to meet emissions without sacrificing performance; while others wanted the lowest possible cost and ease of maintenance. The result is three distinct solutions: PowerTech Plus, PowerTech E and PowerTech M.
Compliance for flexibility and cost-savings
Following a simple design, PowerTech M engines (2.4L and 4.5L) use mechanical controls for optimal performance, while maintaining the performance standards of Tier 2/Stage II engines. They feature a new mechanical injection system that generate high injection pressures and improves combustion efficiency.
Emissions compliance without sacrificing performance
PowerTech E engines are equipped with an HPCR fuel injection system (4.5L and 6.8L), electronic unit pumps (2.4L and 3.0L), a two-valve cylinder head, and integrated electronic engine controls. The HPCR fuel injection system improves combustion by increasing the fuel pressure. Performance and fuel economy are comparable to Tier 2/Stage II engines. PowerTech E engines are built on platforms similar to their Tier 2/Stage II equivalents, so they are easy to integrate into the engine compartment.
John Deere’s Tier 2/Stage II engines meet emissions regulations with a variety of technologies for the engine cooling, control, and fuel systems.
Tier 1/Stage I mechanically controlled engines are still available to deliver the best performance for non-regulated markets.
