Motors - another VW variant.

Recommended Posts

" This VW type engine is the perfect example of what "simplicity" gets you. Low power, poor economy, poor tbo and heavy weights."

 

Well it is a 1930 design !

 

LIGHT weight,

 

Great power to weight,

 

61 U.S. MPG = 3.86 Liters per 100 km, at 100 mph

 

Runs forever,

 

Remove the "Flywheel.

A Honda 100hp outboard engine costs about 14k and is based on the jazz engine, the jazz (the car) costs about 17k, so what would honda charge for a low volume aircraft engine? It would have to be a new design  horizontal engine to gain any traction in the marketplace.

AND Again the OLD is comparable with the new.

 

1940's McCulloch motor of 3 litre, 72 hp @ 4100 rpm, weight 85 lb  8.0 to 1 compression ratio.

 

Runs very Smooth, But very thirsty.

They could charge what Rotax do, IF it beats Rotax on it's weight, performance and economy factors....( It would be turbo charged with altitude normalization)

 

I don't even think they would need to run dual systems to the extent that Rotax does. Surely there is no need for dual redundant injectors in 2019?

One thing of note with this engine is that power is rated as 100 hp at 2900rpm. This would be handy as most VW based engines max power is 3200 to 3600. So a larger prop can be used maximising the lower rpm range AND the higher power output over the normal 76 to 80hp.  Ken
