Internal combustion engines are far from dead and could be in production well into the next decade – and beyond. Over the past year, we’ve seen automakers recommit to gas engine production, among a host of others pushing the boundaries of technology.
The latest innovative engine is from Boreham Motorworks, which is showing off its new Boreham Ten-K naturally aspirated 2.1-litre four-cylinder engine. It produces 324 horsepower at 10,000 rpm and weighs 187 pounds (as shown), which is light compared to others of similar size, especially for street cars.
This will power the brand’s reborn Ford Escort Mk1 RS. The engine features individual throttle bodies, a belt-driven dual camshaft and lightweight internals and billet components including the crankshaft, rods, cradle, dry sump and cam cover. It features Formula 1-inspired port geometry and modern electronics.
Boreham Motorworks says it has saved weight by using thin-walled 3D printed molding technology, which “enables a sculpted engine block that is closely molded around the internal components.”
The engine is undergoing dyno testing and calibration, and according to the company, it is “exceeding development targets for performance”, with power and rev limits already above original targets.
Other companies are also pushing the boundaries of combustion engines. Omoda & Jaecoo introduced one with a thermal efficiency of 48 percent, which could translate into a reduction in fuel consumption of roughly 2.5 percent.
Horse Powertrain, a global supplier of powertrain systems, has introduced a family of range extenders, including a hybrid version that runs on both gas and liquid petroleum. If current trends continue, we expect more innovative combustion engines.
Automakers have also recommitted to producing them well into the next decade, despite earlier promises to quickly switch to building only battery-electric vehicles. Adoption has been inconsistent, so automakers produce what buyers want, and that means the internal combustion engine continues to dominate.
