New Engines

Arrow has announced the addition of three new models to its multi-cylinder VR gas engine line. The model VR 260 is an inline, four-cylinder engine, with a 4.2 L displacement, and is rated 47 hp at 1800 rpm, naturally aspirated. The 6.2 L VR 380 is an inline, six-cylinder engine rated at 80 hp (continuous) at 1800 rpm, also naturally aspirated. When turbocharged and after-cooled, the VR380TA is rated at 115 hp at 1800 rpm.

These new models share heavy-duty industrial engine features such as removable wet sleeves, individual cylinder heads, alloy valves and seats, forged cranks and rods, replaceable guides and a fully filtered, pressurized and cooled lubrication system.

The engines are available with various options and in varied configurations to make them suitable for industrial applications such as generators, compressors, pumps and pump jacks, the company said.

Engine Technology

In response to high fuel prices, Briggs & Stratton Commercial Power is now offering a low-speed operation option on its Vanguard Big Block V-twin engines. Commercial equipment with the low-speed option benefits from increased fuel efficiency, B&S said.

Low-speed operation leverages the torque curve produced by the Vanguard Big Block and reduces engine speed from the standard 3600 rpm to 3200 rpm, increasing fuel efficiency while reducing noise and vibration, the company said.

Briggs & Stratton said the system acts like an overdrive gear in a car --power remains in reserve for situations that require full-throttle application, while most of the time low-speed operation increases fuel efficiency by 10%, decreases noise up to 40% and lowers engine vibration by 20%.

Power Range

Diesel: 11 to 6600 hp

Gaseous Fuel: 95 to 4705 hp

SCR: Yea or Nay?

Caterpillar construction and industrial mobile equipment engines, including those sold to industrial OEM customers, will not utilize selective catalytic reduction (SCR) to meet upcoming U.S. EPA Tier 4 Interim, European Stage 3b and Japan MLIT Step 4 mobile off-highway emissions regulations that take effect in 2011.

Emissions Technology

Caterpillar Tier 4 engine systems will be equipped with particulate matter (PM) aftertreatment technology, including oxidation catalysts and diesel particulate filters with advanced regeneration systems.

New Engines

Caterpillar has announced an expanded compact industrial diesel engine lineup that extends its family of engines from 11 to 6600 hp and offers "a clear path to off-road EPA Tier 4 Interim and EU Stage 3b compliance."

Cat compact diesel engines now cover a range from 11 to 66 bhp with 10 models that meet existing Tier 3/Stage 3a and Tier 4 Interim emissions standards for North America and Europe.

In addition, to simplify installation for OEMs, the line carries over earlier ratings and rated speeds with no engine package size increase.

The expanded compact engine lineup includes the C0.5 diesel rated 11 to 13.7 bhp at 2800 to 3600 rpm; the C0.7 rated 16.4 to 20.5 bhp at 2800 to 3600 rpm; the C1.1 rated 18.4 to 28.2 bhp at 2200 to 3400 rpm; and the C1.5 with outputs from 27.8 to 33.7 bhp at 2200 to 3000 rpm.

Next in the line is the turbocharged C1.5 with ratings from 31 to 40.2 bhp at 2200 to 3000 rpm; the C1.6, rated 33 and 35.5 bhp at 2800 and 3000 rpm; and the C1.7, rated 33.2 and 34.8 bhp at 2400 and 2600 rpm.

The last three models in the line are the C2.2 with ratings from 41.6 to 45.6 bhp at 2200 to 3000 rpm; the turbocharged C2.2 rated 53.6 and 60 bhp at 2600 and 3000 rpm; and the turbocharged and aftercooled model C2.2 rated 66 bhp at 2800 rpm.

These engines feature improved electronically controlled governing, with a new governor design that incorporates optimized lever ratio for improved engine response, improved tolerance and manufacturing of governor components.

Cat said there is a noise reduction of more than 2 dB(A). This improvement in noise is achieved through reduced fan speed, cylinder block redesign, timing case stiffening and low noise fan options. Also new are more efficient cooling and high/low fan position options.
