FOCS Series, 13hp - 39hp CHD Series, 40hp to 87hp FOCS Series, 13hp - 39hp Robust, Sturdy, Minimum Weight The original design concept as the pearlitic grey cast iron cylinder head with integral re borable “twin” arranged liners, with cross flow intake and exhaust, has allowed the reduction of the engine length assuring at the same time an exceptional sturdiness. The LDW 502M, which has been built with an aluminium engine block and reborable liners is the most popular engine in its class. Low Noise Excellent results have been obtained in reducing the noise emissions thanks to the location of the injection system in the cylinder head, to a ribbing system along the engine structure and to the complete absence of gears. The overhead camshaft is driven through a cogged belt, especially designed for heavy duty applications to ensure longevity of belt life. The lubrication system is fed by a “gearator” oil pump driven directly by the crankshaft. High Performance Utilisation of newly developed and “Lombardini patented” unit type injector pumps, in place of a conventional rotary type injection system, incorporating separate injection pumps and injectors allows the elimination of fuel pipes and consequently provides a better injection timing and pressure with the result of more efficient increased performance advantages. Low Exhaust Emissions The “Lombardini patented” injection system has been tested for exhaust emission levels to the lowest limits. FOCS engines achieved high acclaim with regard to exhaust emissions being well below the EEC requirements. Absence of Vibrations The very accurate balancing of the moving components together with optimum combustion allows for low vibration levels at all engine speeds. Low Servicing Costs Components that require more frequent checking are located in the upper part of the engine, just under the rocker cover. This allows easy and low cost equipment maintenance.

The innovative design of the gear train, the injection system and location, and the reduced cylinder pitch, shortens the engine length. Operational Comfort The special crankshaft balancing gives exceptional low vibrations and ensures an excellent operational performance during use. Reduction in noise emission. The innovative design of the fuel injection system, as well as the utilization of hypereutectic pistons which reduce piston slap and a heavily constructed block, assist in greatly reducing noise levels that are normally associated with diesel engines. Performance Individual Unit type injectors offer high performance at all engine speeds. Compared to a conventional injection pump the injection system on the CHD Series feature a one way flow and a unique delivery system that prevents unwanted variations of injection pressure and timing ensuring maximum efficiency during combustion. Environmental Through the design of the injection and combustion system Lombardini have realised an engine that provides maximum power whilst ensuring exhaust emission are kept to an absolute minimum ensuring the protection of our environment. Easy Maintenance All Maintenance operations are made easier due to the simple construction of the product. Also for maintenance of the injection system it is not strictly necessary to involve the services of a pump specialist, but the servicing of parts can be complete by a qualified service outlet.
