Ford working on project to develop low particulate emission diesel cars

Ford is leading a £2.5 million (€3.5m) research project investigating the use of alternative fuels offering customers the power and performance of modern engines with environmental benefits comparable to an electric vehicle.

The German government is co-funding the three-year project that will test the first-ever cars to run on dimethyl ether (DME), commonly used as a non-toxic propellant in aerosol spray gas, and oxymethylene ether (OflME1), a liquid usually used as a solvent in the chemical industry.

Both ethers, which will power cars based on the Ford Mondeo, offer the potential for extremely low particulate emissions and enhanced fuel efficiency. They can be generated from fossil natural gas or bio-gas or through a sophisticated process called power-to-liquid that uses renewable sources such as solar or wind power together with CO2 captured from the air.

This  technology is being investigated in a parallel project together with RWTH Aachen University researching the viability of different DME generation methods, looking at conversion efficiency, estimated fuel prices and infrastructure aspects.

“The CO2 produced by a car powered by DME from renewable sources could be comparable to the amount generated by a marathon runner covering the same distance – but with performance similar to a diesel powered vehicle,” said Werner Willems, technical specialist , powertrain combustion systems, Ford of Europe.

“This is a project that could help place vehicles with a significantly reduced carbon dioxide and particulate emissions on the market at affordable costs.”

Both DME and OME1 produce almost no particulates, and also share characteristics with diesel fuel that are expected to make conversion of diesel engines possible with comparable performance. It is estimated that DME from renewable energy sources could offer well-to-wheel emissions of about 3 g/km CO2.

Like liquefied petroleum gas, DME must be stored in a slightly pressurised tank. OME1 can be stored in a conventional tank system. The DME-powered engines are expected to benefit from almost soot-free combustion, higher thermal efficiency and excellent cold start properties.

    Not diesel cars, but an alternative fuel. Headline is perhaps misleading.
