'Massive Yet Tiny' engine promises big things

[TechZ]

Angel Labs has developed a new type of internal combustion engine known as the 'Massive Yet Tiny' engine.

It "has the potential to replace all the existing internal combustion engines and jet engines," according to the inventor. It reportedly has a power to weight ratio 40 times higher than a regular internal combustion engine. A 14-inch, 150-pound MYT would reportedly have the same power as a 32 cylinder diesel engine - putting out 858 horsepower.

At 150lbs, the basic ME design needs only to produce 3,000 hp from 848 cubic inches to produce a 20 to 1 power to weight ratio. (We are assuming less than 4 hp per cubic inch of displacement. Racing engines based on conventional design perform up to 5+ hp per cubic inch of displacement with Super/Turbo Charge. With Normally Aspirated, it will generate minimum 850 horse powers.) To our knowledge, only the latest jet engine has finally attained a 20 to 1 power to weight ratio. By replacing the rear cover of the ME and connecting another ME chamber assembly (adding two inches in length and little additional weight) the ME now becomes a 64 cylinder engine with 1,695 cubic inches raising the power to weight ratio up to 40 to 1. Since the ME lacks the 80% of the parts normally found in a reciprocating internal combustion engine that is responsible for high friction and parasitic losses, this normally dormant horsepower is now available and would increase the total deliverable output of the ME.

Normally, in a compression ignition (diesel) engine, combustion begins @ TDC (Top Dead Center) @ 0 degree crankshaft position. The expanding gases push the piston down on the power stroke, rotating the crankshaft 180 degrees. The piston then returns to TDC pushing the exhaust at the exhaust stroke, rotating the crankshaft another 180 degrees. This is the burning time in a standard engine, a total of 360 degrees duration.

On a dynamometer, an engine's combustion temperatures is typically measured 2″ from the exhaust ports, on the premise that the combustion temperature is very close to exhaust temperature. This is due to the zero degree duration @ TDC and the 360 degrees running duration of a standard engine. However, if @TDC, the piston is allowed to stay for a longer duration, it will burn a greater percentage of the fuel and air mixture in the combustion chamber until oxygen or fuel theoretically runs out at the end of the power stroke, thereby totally completing the combustion process and drastically lowering the exhaust temperature at the end of the exhaust stroke.

The ME design permits the piston dwell @TDC to be adjustable and the prototype ME is currently set at approximately 12 degrees of the crankshaft rotation, thereby approaching the perfection of a complete burn of all fuel. Its exhaust gases are much cooler. As a result:

- More energy is harnessed for the same amount of fuel and air input.
- There is less left over fuel to continue to burn at the exhaust stroke.
- There is less waste and pollution

German Loremo AG introduced the Loremo (homepage), their ultra efficient car. Founded in 2000, this new company developed a light-weight passenger car with outstanding aerodynamics. The one, two combination of light weight and tunnel tested aerodynamics allow this car to travel 157 miles per gallon of gasoline or 1.5 l per 100km!

Of particular note is the rear differential-link axle, specially-developed for the Loremo, which combines the advantages of longitudinal- and semi-trailing link axles. With maximum load, the axle is indifferent to toe and camber at full suspension compression. In curves, however, the wheel leans inwards to achieve better lateral traction. An optimal load distribution of 50:50 is achieved by placing the motor centrally and 105/70 R14 low-profile tires give good road holding and perfect straight-line driving.

The 20 PS (15 kw) two-cylinder turbo-diesel motor powers the 450 kg (204 lb) light Loremo LS to up to 160 km/h (100 mph). It accelerates from 0 to 100 km/h (63 mph) in 20 s and its aerodynamic form achieves a Cw value of 0.20. Fuel consumption: tiny 1.5 liters for 100 km (157 mpg)! Thus the Loremo can travel from Munich to Rome (over 800 miles) on only one 20 liter (5 gallon) tank of fuel. At only 384 cm (151 in) long, 136 cm (62 in) wide, Loremo AG has developed a true small car. In driving fun the 110 cm (43 in) flat, economical sports car easily runs against the large competitors and all for a purchase price under 11.000.- €

Those who want more should look forward to the Loremo GT. With 50 PS (37 kw) and a 3-cylinder turbo-diesel motor it reaches a top speed of 220 km/hr (138 mph). And with 2.7 liter for 100 km (88 mpg) it is still very fuel-efficient. The price will be under 15.000.- €

nice idea ...now how do you cool it
