In its new report on downsized and boosted gasoline engine technologies ( earlier post ) the ICCT highlighted Ricardo’s work on an “extreme” Miller cycle concept with high (13:1) compression ratio (CR) and central direct injection in a downsized boosted engine. A long exhaust stroke then extracts maximum efficiency. Resources.

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,

Thrust 1 builds on the significant amount of work carried out over the past several decades, focused on building advanced boosted, downsized, and downspeeded spark ignition engines. We’ve been accused of that; people still say we are, but we’re not. We’re not going to say “Ethanol. Ethanol is the answer.”

We’re focused on the customers’ most critical issue—smaller packaging. Eaton said that a series of process improvements and new engine valve product designs will help engine manufacturers address issues related to engine downsizing to achieve better fuel economy and reduced emissions. —Dave Genise.

The combination of electronics, advanced battery technology and charging techniques ensures the system can deliver the required rapid charge and discharge performance, while at all times maintaining a stable 12 volts to the vehicle’s main electrical system. Hence the industry trend to dual-charging systems, CPT notes.

To keep the engine unit as small as possible, the exhaust manifold is integrated within the cylinder head and can therefore be cooled efficiently using the cylinder head water cooling system. liter T-GDI engine incorporates a high-pressure single-scroll turbocharger integrated within the exhaust manifold to improve operational efficiency.
