Mazda Commences Production of Mazda CX-5 with New-Generation Super Clean SKYACTIV-D Diesel Engine

Tuesday, January 31st, 2012

HIROSHIMA, Japan — Mazda Motor Corporation commenced production of the all-new Mazda CX-5 with its new-generation SKYACTIV-D 2.2-litre, super clean diesel engine at its Ujina Plant near Mazda’s headquarters in Hiroshima. The CX-5 will be the first model of the company’s new-generation products that adopts SKYACTIV TECHNOLOGY throughout the vehicle, in the powertrain, body and chassis, while fully embracing Mazda’s new design theme, “KODO – Soul of Motion.” Mazda will start introducing the Mazda CX-5 this spring in Japan, Europe, followed by other markets around the world.

Mazda’s SKYACTIV-D 2.2 diesel engine is the world’s first* diesel engine to comply with global exhaust gas regulations, including Japan’s Post New Long-Term Regulations and Europe’s Euro6, without the need for an expensive nitrogen oxide (NOx) aftertreatment system, such as the urea selective catalytic reduction (SCR) system or Lean NOx Trap (LNT) catalyst. By precisely controlling fuel injection and improving the exhaust valve’s opening and closing mechanism, the SKYACTIV-D diesel engine has achieved breakthroughs to resolve longstanding issues encountered in low compression ratio engines, such as poor start capability and lower combustion stability when the engine is cold. These improvements helped to achieve the world’s lowest* compression ratio of 14.0:1 for a diesel engine for mass production vehicles.

Through its pursuit of ideal combustion using engineering innovation, Mazda has achieved not only outstanding emissions performance, but also excellent fuel economy and ample torque equal to a 4-liter V8 gasoline engine.

With the introduction of the Mazda CX-5 with the SKYACTIV-D diesel engine, Mazda is offering a fresh, fun-to-drive option to the eco-car market – an option that also combines outstanding environmental performance and pioneers a new era of diesel power.

New lightweight Suzuki DF20A/15A makes world debut at Düsseldorf

Tuesday, January 24th, 2012

0123 01 Suzuki announced the launch of two new fuel-efficient and high performance four stroke outboard motors – the all-new DF20A and the new generation DF15A.These new models, which made their world debut at the Düsseldorf Boat Show on the 21st January 2012, will be the first in their class to feature battery-less Electronic Fuel Injection.

The new Electronic Fuel Injection system will also be combined with Suzuki’s Lean Burn Fuel Control system, which will result in a number of benefits for boaters such as; easier starts, more responsive acceleration, smoother performance and above all, greater fuel efficiency.

To achieve this, Suzuki engineers have designed a completely new fuel injection system for these models, which includes; an inline high-pressure fuel pump, a throttle body and small fuel cooler, vapor separator and fuel injector. By designing these component parts to be smaller than those used on larger Electronic Fuel Injection engines (DF40-DF300) the overall weight of these new models has also been kept as low as possible.

According to Suzuki’s internal testing, this means that at just 44kg the new models will be the lightest and most compact outboards in their class.The compact size and light weight of the new DF20A and DF15A make them an ideal power match for a wide variety of boats, including; small RIBs and tenders, day boats for in-land waterways and small fishing boats to name but a few. In particular these new outboards will be ideal for entry level boating.

Hyundai Injects Veloster with New Turbocharged Engine

Monday, January 16th, 2012

Hyundai Motor America has introduced the all-new 2013 Veloster Turbo armed with 150 kW of peak power in a world debut at the North American International Auto Show (NAIAS).The 1.6-litre turbocharged GDI four-cylinder engine in the 2013 Veloster Turbo produces 150 kW @ 6000 rpm and 264 Nm of torque from 1750 – 4500 rpm with standard unleaded fuel. The Veloster Turbo is estimated to deliver 8.7 L/100km city and best-in-class 6.2 L/100km highway for manual transmission models. Hyundai’s 1.6-litre Gamma turbocharged engine features a twin-scroll turbocharger that when combined with the GDI system, results in instantaneous power delivery.

Twin-scroll turbocharger designs have two exhaust gas inlets divided by split walls inside the turbine housing, with both gas passages controlled by a waste-gate. A twin-scroll turbo recovers more energy from the exhaust than a single-scroll turbocharger, thanks to a divided manifold. The twin-scroll design separates the cylinders whose exhaust gas pulses interfere with each other, resulting in improved pressure distribution in the exhaust ports, and a more efficient delivery of exhaust gas energy to the turbocharger’s turbine. Another advantage is improved low-end torque and faster transient torque response.

Thanks to the integrated stainless-steel turbine housing with the exhaust manifold, not only is the weight and cost of the casting dramatically reduced, the durability of the turbine housing is also improved. In addition, heat energy recovery and thus turbo efficiency is significantly improved based on the fact that a traditional two-piece design effectively insulates some of the heat energy at the joint/gasket area.

By adapting the motor-driven electrical waste-gate, the boost pressure is precisely controlled. The back pressure is reduced when turbo boost is not necessary by opening the waste-gate, which improves fuel efficiency. During cold starts, the waste-gate remains open, which results in faster catalyst light-off for reduced exhaust emissions.

A GDI fuel delivery system contributes to improved fuel efficiency and lower emissions. This shorter, more direct path of fuel delivery allows for greater control of the fuel mixture at the optimum moment, thus improving efficiency. The fuel is injected by a camshaft-driven, high pressure pump operating at pressures up to 2175 psi. Direct injection also utilises a higher-than-normal 9.5 compression ratios, while achieving a best-in-class93.6 kW-per-litre. The piston heads are “dished” to increase combustion efficiency in the cylinder.

DETROIT -Nissan and Daimler will produce Mercedes-Benz 4-cylinder gasoline engines together at Nissan’s powertrain assembly plant in Decherd, Tenn. Production will begin in 2014, with installed capacity of 250,000 units per year once full ramp-up is achieved. The Decherd facility will produce engines for Mercedes-Benz and Infiniti models.

This is the newest milestone in our pragmatic collaboration and our most significant project outside of Europe so far,” said Renault-Nissan CEO Carlos Ghosn. “Localized capacity reduces exposure to foreign exchange rates while rapidly enabling a good business development in North America – a win-win for the Alliance and Daimler.

The collaboration marks the first production of Mercedes-Benz engines in the North America Free Trade region. The Tennessee plant’s strategic location and logistics links ensure a direct supply of engines starting in 2014 for the Mercedes-Benz C-Class, built at Daimler’s vehicle plant in Tuscaloosa, Ala.

In the context of our Mercedes-Benz 2020 growth strategy, we have decided that we will expand the production capacities required for this close to the customers. Through the strategic extension of our cooperation with Renault-Nissan we can realize near-market engine production in the NAFTA region on attractive economic terms and make optimum use of synergies arising from the cooperation,” Dr. Dieter Zetsche, Chairman of the Daimler Board of Management and Head of Mercedes-Benz Cars, said. “Thus we are systematically broadening our manufacturing footprint in this important growth market.

Nissan began powertrain assembly in Decherd in 1997. it manufactures 4-, 6- and 8-cylinder engines for the complete lineup of U.S.-produced Nissan and Infiniti vehicles. The plant also houses crankshaft forging and cylinder block casting operations. In 2011, Decherd produced more than 580,000 engines on a covered area of more than 1.2 million square feet (111,000 square meters).
