![]() ![]() The Apollo project includes the following enhancements: New design oil pump with reduced internal leakage and reduced frictionĬhrysler Group engineers used the same incremental approach to fuel efficiency improvements in the Dodge Durango SUV fuel efficiency demonstration vehicle. Design changes to lower friction at no extra cost: Crankshaft offset, Reduced oil-ring tension, Shortened coolant jacket This also enables increased EGR (Exhaust Gas Recirculation) Use of swirl control valves to enhance flame propagation during warm-up and partial load. Increased compression ratio (4 percent) through intake port air-gap thermal barrier (patent pending). ![]() Total additional costs for project Apollo are only about $500 per vehicle. That vehicle, project Apollo, achieves an overall improvement in fuel efficiency of 25 percent. "The idea of the MAGIC engine is to package them all together so the overall gain is significant."Īs a next step, Chrysler engineers packaged the MAGIC engine into a Dodge Durango SUV with several additional design changes to enhance fuel efficiency. "Most of these changes are not new, and individually, they produce miniscule gains in fuel efficiency," Moore said. Today we can say that it all works."Įight different design and engineering changes were made to the standard engine. "Our goal was to demonstrate that all these little changes actually work in the real world and add up to major improvements in efficiency. ![]() "We call it the MAGIC engine, but it's really pure engineering," said Thomas Moore, Vice President and head of the Liberty & Technical Affairs advanced technology research group in Rochester Hills, Michigan. The improvement in fuel efficiency was achieved with no sacrifice in emissions, power, cost, weight, engine life or other engine characteristics such as noise, vibration or harshness. The project has been nicknamed the MAGIC engine, which stands for Multiple Approaches to Great Internal Combustion. The cost of those changes: less than $200 per engine. With a series of engineering changes to Chrysler's standard gasoline-powered, 4.7-liter V-8 engine, researchers have produced an engine with 14 percent better fuel efficiency. JChrysler Group researchers are using a series of small steps in engineering to produce a giant leap in fuel efficiency that could benefit consumers in the not-too-distant future.
