A breakthrough in Diesel Technology: The twin Crankshaft by NEANDER
NEANDER has developed a technology that eliminates the vibrations of diesel engines: The twin crank shaft.
This enables the manufacturing of particularly powerful turbo diesel engines with few cylinders and can therefore be built particularly compact and lightweight.
A few working prototype bikes and engines with the twin crankshaft technology were built from scratch and did everything that was expected.
The engine, a twin cylinder arrangement with almost 1,400 ccm, was designed with a counter rotating dual crankshaft assembly in order to reduce mass forces and roll torque towards a drivable level.
However, due to the high supplier density in the motorcycle sector, the investment in series production of the motorcycle was not made.
THE TECHNOLOGY‘S PROOF OF CONCEPT IN THE MOTORCYCLE OPENED SEVERAL NEW OPPORTUNITIES: MEETING ECOLOGICAL REQUIREMENTS, REDUCING NOISE & VIBRATIONS, REPLACING HEAVY PETROL OR DIESEL ENGINES.
The Neander technology enables many mobile and stationary applications to replace petrol or heavy multi-cylinder diesel engines by a light-weight turbo-diesel engine of similar power for the first time. This brings extraordinary advantages for users and also meets the ecological requirements of the future.
Further application areas for this innovative technology are Personal Watercrafts, Snow Mobiles, ATVs/UTVs, Ultra Light Aircrafts, Tractors, Generators and Commercial Outboards.
COMMERCIAL SHIPPING HAD NO ALTERNATIVE TO THE CONVENTIONAL PETROL ENGINE IN THE OUTBOARD ENGINE SEGMENT IN THE CLASS UP TO 150 HP.
In the entire area of motorised shipping, diesel is the first choice as fuel compared to gasoline for reasons of lower operating costs, improved availability (fuel logistics) and reduced risk of fire or explosion.
The lower fuel consumption of diesel engines compared to petrol engines of the same size and performance also leads to a significantreduction in environmental impact in terms of CO², HC and NOx emissions.
However, the diesel principle has not yet been able to establish itself in the field of outboard drives because older diesel engineconcepts on the market generate very high vibrations and noise compared to petrol engines and have an unfavourable power-to-massratio. The Japanese company Yanmar produced outboard diesel engines up to 36 hp from 1987 to 2007. However, these engines couldnot be established on the market in the long term since 2007 due to the disadvantages mentioned above and changes in emissionslegislation, so production was discontinued.
YANMAR DISCONTINUED PRODUCING DIESEL OUTBOARD ENGINES IN 2007. THERE WAS AN OPPORTUNITY TO FILL THE GAP: NEANDER FOCUSSED ON A NEW TURBO-DIESEL OUTBOARD ENGINE.
DEVELOPING THE WORLD‘S FIRST TURBO-DIESEL OUTBOARD ENGINE UNDER 100HP: DTORQUE 111
The 50 hp outboard market segment for commercial boat applications was identified to be optimal for introducing a new turbo-diesel engine with convincing advantages:
- high performance at low RPM
- vibration free, low noise
- one fuel, increased safety
- excellent cost of ownership
