Quite rightly, haulage companies are demanding higher and higher standards in truck diesel design, particularly at the heavy end of the market. As far as we're concerned, continual development is the only way to meet their demands.
For instance, every Eagle cylinder head is air-flow tested before assembly to ensure smoke-free operation. Efficient porting, increased outlet manifold diameter and swirl inducing crescents combine to improve the combustion efficiency. So fuel economy is improved and exhaust temperatures are lowered.
This typifies our attitude to design and development: make the engine better but don't complicate it. And it's the reason for the impressive reliability of our engines.
The basic design is very simple. The components are extremely strong; probably stronger than they really need to be. And whatever we don't make ourselves has to be well proven, to maintain the kind of quality a RollsRoyce must have.
But quality isn't the only result of features such as these. Rolls-Royce Eagle engines are also very economical, both in terms of fuel consumption and long term efficiency and reliability. And the implications of that don't need to be spelt out.
If we weren't so fastidious we could build a lot more engines and make a lot more money. For a while.
But we'd rather have demanding customers than no customers at all.
