Alcohol Boosting Enables Significant Downsizing of Heavy-Duty Diesels to Smaller Gasoline Engines

Posted on August 09, 2008

Using a direct-injected alcohol fuel as a second, boosting fuel can allow a turbo-charged, high-compression ratio spark-ignited gasoline engine to replace larger diesels in certain heavy-duty applications, according to work being done by Ethanol Boosting Systems, LLC (EBS), a spin-off from MIT. (Earlier post.) A study by EBS supported by Volvo Powertrain North America found that for a given engine size, an alcohol-boosted gasoline engine (spark-ignited, SI) could operate with about twice the torque and at higher horsepower than a baseline diesel. In a study presented at the DEER (Diesel Engine...
