New Engines

Arrow Engine Co. has introduced the VR260 and VR380 industrial natural gas engines. The new series are wet sleeved, water-cooled engines that will operate at 900 to 1800 rpm with an output of 26 to 80 hp. The wet sleeve and individual head design ensures field rebuild ability to avoid downtime and excessive transportation costs to the end users, Arrow said.

The VR260-380 will come standard with electric start, solid-state ignition system, and electronic governor. There is a full line of accessories available from base engines to complete power units. The turbo version of the VR380 will be introduced early fall of 2007.

New Engines

Briggs & Stratton Commercial Power will offer its first engines equipped with electronic fuel injection (EFI) in 2007. The new gasoline-powered EFI model will be an extension of the company's Vanguard 3/LC three-cylinder, liquid-cooled engine line.

Developed in conjunction with Daihatsu, the 34 hp Vanguard 3/LC EFI engine is capable of delivering increased fuel economy--up to 30% fuel savings, depending on duty cycle--with increased responsiveness at all engine speeds. The EFI system automatically adjusts engine settings in real time for quick, no-choke cold starts and to compensate for altitude and environmental variables. This provides optimized power and drivability in a variety of conditions, Briggs said.

Engine Technology

The Vanguard 3/LC EFI employs a 32-bit engine control unit (ECU) designed to provide responsive performance with enhanced drivability. Onboard diagnostics built into the ECU provide quick, accurate troubleshooting for reduced equipment downtime, Briggs said, and all ECU and EFI components in the Vanguard 3/LC system have been proven through use in automotive applications.

The new 3/LC EFI engine is the latest addition to the Vanguard 3/LC line of three-cylinder, liquid-cooled engines in the 18 to 34 gross hp range, in gas, diesel and turbodiesel configurations.

New Engines

The past year saw Caterpillar's commitment to providing compact engines fulfilled. Three new compact, emissions-compliant diesel engines intended for use in small and midsize construction, agricultural, turf and outdoor power equipment were introduced.

The year also saw the rounding off of the company's Tier 2/Stage 2 and Tier 3/Stage 3a compliant diesel engines with ACERT Technology intended for the industrial and off-highway markets.

The new C1.5, C1.7 and C2.2 diesels are available in naturally aspirated, turbocharged and turbocharged/ aftercooled configurations, and complement five previously announced engines in Cat's compact diesel lineup. With the new engines, Cat compact diesels now cover the range from 11 to 80.5 hp with eight engines meeting existing Tier 3/Stage 3a emission standards for North America and Europe, and are designed as solid core engine platforms to tackle future emissions requirements.

The engines in the Cat compact diesel product line are: C0.5 rated 11 to 13.7 bhp at 2800 to 3600 rpm; C0.7 rated from 16.4 to 20.5 bhp at 2800 to 3600 rpm; C1.1 rated from 18.4 to 28.2 bhp at 2200 to 3400 rpm; C1.5 rated from 27.8 to 40.2 bhp at 2200 to 3000 rpm; C1.6 rated 33.0 to 35.5 bhp at 2800 to 3000 rpm; C1.7 rated 33.2 to 34.8 bhp at 2400 to 2600 rpm; C2.2 rated from 41.6 to 66 bhp at 2200 to 3000 rpm; and C3.4 rated from 57.6 to 80.5 bhp at 2600 rpm.

Cat said the engines have 500-hour maintenance intervals and single-side service access designed to reduce the total cost of ownership. The engines are engineered to meet the specific needs of the small and midsize equipment market, Cat said, with most offering a choice of high- or low-mounted fans, special low-noise fans, and electronic governors that extend engine life in many applications.

Emissions Technology

To date, more than 15,000 Caterpillar engines equipped with ACERT technology have been sold by Caterpillar's Industrial Power Systems, and are now in use in industrial applications and on off-road machines around the world. Cat said Tier 3/Stage 3a compliant engines with ACERT Technology include the C4.4, C6.6, C7, C9, Cll, C13, C15 and C18 single-turbo models rated 575 to 630 bhp.
