Cummins Launches New QSB Engine at ConExpo

Cummins has launched their next-generation QSB engines which feature enhancements for superior performance, durability and reduced noise. These engines not only meet the Environmental Protection Agency (EPA) Tier 3 emissions requirements, but are fully capable of moving forward to the future Tier 4 requirements.

Cummins QSB engines feature advanced electronics, new sculpted blocks, rear gear trains, and High-Pressure Common-Rail fuel systems. The QSB will be available in both a four- and six-cylinder platform. The engines are rated from 110-275 hp (82-205 kW) and are specifically designed to meet the durability, reliability and power density requirements of premium applications such as excavators, materials handling equipment and cranes where high performance is essential at every site.


"We've enhanced the QSB with some evolutionary durability and reliability updates which move the engines significantly ahead of the competition. Cummins in-cylinder emissions solution has enabled increased performance while meeting regulations without the use of complex turbocharger arrangements or external hardware such as exhaust gas recirculation," said Dave Crompton, Cummins Vice President - MidRange Engine Sales. "These upgrades ensure long-term platform stability for the OEM beyond 2011 with the addition of aftertreatment. Cummins is focused on providing engine platforms, customer support and technology to the construction market that are second to none in the industry every time," he added.

Engine sociability is becoming important not only in North America, but in some areas of the world noise levels are being legislated. To meet these new and impending requirements, Cummins has incorporated many enhancements that significantly reduce the noise level of the engines by as much as 9 dBA. The new QSB utilizes a rear gear train, an enclosed valve tappet cavity, and a sculpted block to reduce the noise level such that the Tier 3 engine is as quiet at full load as its predecessor was without load. This is a benefit not only for meeting global requirements, but also enhances the operator's experience and reduces the potential for fatigue and distraction due to high noise levels.

Cummins stated that the QSB engine is backed by Cummins industry-leading QuickServe Guarantee program. Cummins QuickServe offers factory-certified technicians the most sophisticated diagnostic and repair tools in the industry and the largest international parts and service network of any engine manufacturer.

Kohler New Engine Line Introduced

Kohler has introduced KOHLER Courage engines. These engines offer the most displacement and powerful output of any single-cylinder engine available on the market.

Kohler courage engines are available in six models up to 20 HP, the vertical-shaft KOHLER Courage provides OEMs in the consumer turf market a cost efficient premium engine with unique, marketable technologies including a patented dual-cam design and crossflow cylinder head. In addition, KOHLER Courage features full-pressure lubrication, a tri-phase air induction system and a ported-power intake, all patent pending. The Courage line, which exceeds current EPA and CARB emission standards, also features an OHV design, electronic ignition, cast-iron cylinder liner, and a patent pending reciprocating balance system. The new balance system decreases in-line and side-to-side unbalanced forces to minimize vibration.

The engine's uniquely designed inverted crankcase eliminates the oil leaks and provides simple, no mess removal of the automotive-type full flow oil filter.

Multi-functional components include a computer-designed ported power intake, which creates air/fuel mixture tumble in the cylinder for highly efficient combustion.

In addition, the KOHLER Courage engine features an air filter that is 39% larger than competing models with comparable horsepower. The unique design not only provides users with a long-lasting air cleaner, but also contributes to a quieter running engine.

KOHLER Courage is designed to be consumer-friendly and easily adapted to existing turf models. The engine's major external components, including the air filter, oil filter and dipstick, are all located in easily accessible positions. The oil fill and dipstick are integral and designed with an extra wide opening for fast, no mess oil changes.

Cummins Onan Boosted By Coastal Trade

Engine distributor, Cummins Diesel (also known as Cummins Onan) is a supplier of marine engines, auxiliary generator sets, marine products. Reports say maritime trade around the coast of southern Africa is stimulating business growth for Cummins as well as port auxiliary vessels, tugs, fishing boats, work-boats, leisure craft and tourist cruise vessels who are being serviced by Cummins’ newly enlarged marine upfit centre.

Cummins’ marine support network goes around the entire southern African coastline but Cummins Onan services destinations far beyond those ports for emergency calls. Cummins workers have been called out to re-power service rigs off the Ivory Coast in West Africa, and to the Seychelles Islands in the western Indian Ocean to supply power units for cargo barges.

The Cummins Onan marine diesel product line expanded to include the largest engine to be manufactured by Cummins, the QSK60M, a 16-cylinder unit producing 1716Kw @ 1800 rpm, and in the the lower-horsepower range are the Cummins QSB5.9M, QSC9M and QSM11 electronic engines, designed for pleasure or commercial boat use.
