Since internal combustion engines will remain the primary mode of choice for mobility in the foreseeable future, both alternative (renewable) fuels and high-performance combustion concepts/ engines using fuels adapted for that purpose will be preferred for reducing the combustion impact on climate change.

Dutch start-up ECONAMIQ is developing a novel engine technology which saves up to 20% in fuel consumption. The “ECONAMIQ principle” uses flexible over-expansion in combination with cylinder deactivation technology to increase performance and efficiency without significantly changing the engine layout or architecture.

A collaboration between research teams at Shell and Gordon Murray Design (GMD) recently led to the development of an innovative concept engine lubricant capable of achieving a 6.5% improvement in fuel efficiency on an urban cycle, and a 4.6% benefit on a combined cycle. Using GMD’s new T.25 A hat-tip to Ray!).

The only entry criteria for innovations are that they reduce CO 2 emissions from passenger cars; could be commercially deployed in 3–5 years; are on-vehicle, and; are compatible or could be easily integrated into the existing transport, energy and fuel infrastructures. The Exhaust port is located on the outer side of the engine block.

The combination of discrete, asymmetrically sized cylinders and fully variable valvetrain promises the ability to vary displacement ratios, bore-stroke ratios, compression-expansion ratios, compression-expansion phasing, and gas transfer phasing for engine optimization—i.e., a more efficient internal combustion engine.
