As well as being lighter and smaller, it features greater efficiency and power.
These extreme downsizing indicates the potential of a SI, knock-free engine, operating at the same peak pressure as the diesel engine and higher engine speeds. However this aggressive downsizing may not be practical because other constraints (durability, exhaust temperatures). In this manner a 3.6 —Bromberg and Cohn.

The two overhead camshafts actuate 16 intake and exhaust valves.
The design brief for the new-generation PureTech engines called for a clean break in powertrain development. To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. Depending on the model and the tires fitted, combined cycle fuel consumption for the new family is between 4.3
LSPI is considered an impediment to aggressive engine downsizing to reduce carbon dioxide emissions. Low-speed preignition events are random, infrequent occurrences that happen at low speed and high torque, and their causes are not completely understood. Earlier post.). When you ignite the fuel too early, you have very high knock.
Researchers at KAUST’s Clean Combustion Research Center have developed a method to predict and to avoid undesirable combustion events in advanced engines, such as knocking and super-knock. Advanced low-temperature-combustion (LTC) strategies of downsized and boosted engines are capable of offering ultra-low emissions and higher efficiencies.
The current decline is ales of diesel light duty vehicle in Europe does not put EU CO 2 targets out of reach of automakers, according to a new analysis by the International Council on Clean Transportation (ICCT). For instance, hybrid electric vehicles and diesel cars in the small (e.g., Renault Clio) and lower medium (e.g.,
First of all, future passenger vehicles have to stay as clean as the best vehicles out there today. We see dramatic downsizing and boosting [as] something that’s going to for gasoline engines especially. To be able effectively to implement downsizing and downspeeding, good low-end torque is essential. smog and particulates.
Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines. Earlier post.).
The SIA conference was focused on clean compression-ignition engines of the future. The vehicles on which the research was based were representative of current production models at the more aggressive end of the downsizing spectrum in terms of engine capacity and output, but modeled with a future three cylinder 1.5 liter diesel engine.
Technologies such as cylinder deactivation (CDA), high efficiency variable geometry turbochargers with exhaust gas by-pass, and start-stop systems are only some of the commercially available fuel saving technologies that can be implemented by 2024. The cost of controlling NO x to 0.05 g/bhp-hr in 2024 and to 0.02 Credit: MECA.
The Dearman liquid air engine is an innovative heat engine that uses liquid air (or liquid nitrogen) as a “fuel” and emits cold air as exhaust. After each expansion cycle the heat exchange fluid is recovered from the exhaust and reheated to ambient temperature via a heat exchanger similar to a conventional radiator. Earlier post.)
An all-new engine architecture delivers reduced friction and a clean-burning combustion system. A short-loop exhaust gas recirculation channel is incorporated into the cylinder head, contributing to a more compact engine design and helping optimize cooling of gasses. Low friction, sophisticated combustion. Enhanced refinement.
This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. Founded in 1976, MECA is a nonprofit trade association of the world’s leading manufacturers of clean technology solutions for all mobile sources. —MECA Executive Director, Rasto Brezny.
A 2025 CO 2 target of an average 70 g/km for new cars in the EU could be met with very little electrification and with an average payback period of less than 4 years, according to a new study by the International Council on Clean Transportation (ICCT).
liter turbocharged gasoline engine has a combination water-cooled cylinder head, integrated exhaust manifold and twin-scroll turbocharger. To minimize turbo lag, the four-into-two exhaust manifold system pairs cylinders according to their expansion or compression stroke to reduce pumping losses and eliminate exhaust gas interference.
A key part of the overall efficiency gain is the downsized 11-liter Volvo engine, featuring advanced fuel injection, cooling, oil and turbo-charging systems, as well as new “wave” pistons and other improvements. This new design added “wave” bumps on the side of the piston bowl, which allows the fuel to burn more cleanly.). for the D13.
By combining High Efficiency Clean Combustion (HECC) and Waste Heat Recovery (WHR), each demonstrating greater than 10% improvement in BTE, together with other technologies, it should be possible to improve BTE by 20% to achieve the original DOE target of 50% peak BTE.

Aeristech’s 48v eSupercharger has already been demonstrated by MAHLE Powertrain UK in a D-segment appraisal vehicle using its downsized turbocharged 1.2 Because it is applied to the inlet side of the engine, it reduces the thermal mass in the exhaust stream which helps to maintain catalyst temperature, especially at lower speeds and loads.
While the Niro Hybrid was preceded by clean mobility products such as the Optima Hybrid and Soul EV, Niro is the first Kia to make use of an all-new, dedicated eco-car platform and is an important next step on the path to nearly tripling the brand’s global green car line-up by 2020. A compact and lightweight 1.56-kWh
Engine downsizing and down-speeding are well suited to take advantage of higher-octane fuels because these engines encounter the knock limit more frequently. Operation under boosted conditions is essential to Co-Optima’s Thrust I effort to maintain acceptable power density for downsized and downsped SI engines.
High-research octane number (RON) fuels are known to enable more efficient, higher-performance SI operation via engine downsizing and boosting. Thrust II will provide the science and technology underpinnings needed for industry to develop advanced, highly efficient, clean-burning ACI engines and the fuels that enable them.
Since the pistons cyclically expose or occlude the exhaust and intake ports, there is no valve train. Because the intake and exhaust ports are at the opposite ends of the cylinder, opposed-piston engines have efficient, uniflow scavenging. Scavenging continues until a 230° crank angle, at which time the exhaust ports close.
Focused on meeting a growing customer demand for ‘downsized’ engines offering strong power with reduced fuel consumption and CO2 emissions, the new gasoline and diesel powertrains are being progressively introduced across the Opel product range. The engine retains the proven concept of a turbine-integrated exhaust manifold.
The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. In fact, the optimized PHEV is much more efficient as a long range liquid fuel vehicle, because the engine is downsized. by Professor Andrew Alfonso Frank. CTO Efficient Drivetrains Inc.
The framework is deliberately designed to prevent downsizing , even though manufacturing smaller vehicles is the best strategy for reducing CO2 emissions. The ability to purchase compliance by buying excess credits from responsible manufacturers further undermines the effectiveness of the framework.
