The greatness of this machine, can use various types of fuel. Withits light weight, density yield twice the power 4-stroke engineConventional (same capacity). Dump gas emissions are also low, unable to meetstrict standards of various countries. Therefore, not surprisingly, Microsoft's boss,Bill Gates is willing to invest the money for further development of the enginethis.
Reportedly, the machine named "opposed-piston opposed-cylinder" (OPOC)This, now in the stage of the optimization of combustion processes. EcoMotors theonly two years old, obtaining funds of U.S. $ 23.5 million from its main investor,Vinod Khosla and Bill Gates to continue to develop a machine that is expectedprospects are very bright.
Generation-6"The sixth generation OPOC machine has reached the stage of tests on the dynamometer," saidEcoMotors CEO, Don Runkle to Automotive Engineering International magazine.He estimated, the test results can be obtained next year.
OPOC designed using the direct injection system. No less interestingalso equipped with a turbocharger and was ready to be produced in two ornext three years.This machine uses a modular basis with various diameters architect. Todayused the diameter of the piston 100, 75, 65 and 30 mm. Each "power modules",cylinder with a pair of opposite horizontal position, using two pistons.Both the piston works through a pair of handlebars piston (con-rod) and shortlength of which is connected to the crankshaft. Piston with opposite posisusing the same combustion chamber in each cylinder. Engine power can beincreased further by adding a set of cylinders."Dynamometer test extensively for the diesel version (diameter 100 mm),showed lower emissions. Machine working efficiency is very high.Power generated in accordance with the calculation, "said Runkle.
Previous tests have shown, the engine fuel efficiency 50 percent OPOCbetter than a conventional engine with the same capacity. While the versionsgasoline is also being tested!
Electric CarsEcoMotors expect this machine can be used for commercial purposes andmilitary (diesel fuel). Because of that, the company's existinginterested in using it for a medium-size trucks. While the machine OPOCsmall capacity, considered suitable for an electric car with an additional generator(Series hybrid).
It is said also, the aerospace industry also benefited from the enginethis. Apart from the high energy density, light weight, economical materialsfuels, the amount of material used is much less.
Currently, two OPOC diesel engine already used on helicopter conceptcalled "bluecopter" hybrid-electric by a consortium of European helicopter, EADSand introduced at the Berlin Air Show in June.
The development of machine OPOC still being conducted. among othersdetermine the upper corner of piston, the number of injectors that will be installed oneach cylinder, angles, shapes and spray pressure and turbochargercontrolled electrically.
