Briggs & Stratton

Briggs & Stratton Commercial Power recently launched four new Vanguard single-cylinder engines with a single lever, the Transport-Guard system. With the flip of a switch, operators simultaneously shut off fuel and the ignition, preventing oil dilution. Ranging from 5.5 to 10.0 gross hp, features include: a high-mounted canister-style air cleaner with 22-percent more filter area; an all-metal fuel tank mounted directly to the engine block to reduce emissions and add durability; and a water-repellant air filter, protected by a full metal cage with a triple-seal design to decrease dirt, dust and debris intake.

Perkins Engines' 1200 Series provide power range from 60kW to 225kW (80 to 300 hp). The 1206E-E70TTA (300 hp) represents a 21-percent increase in power compared with Perkins' current 6.6-liter offering. The model is fitted with two turbochargers. The 1206E-E66TA is a 175-hp engine. Both 1206 models utilize a diesel oxidation catalyst and diesel particulate filter to ensure compliance with particulate emissions regulations. The new 1204 model replaces the 1104 and is offered in two versions: the turbo, intercooled version — the 1204E-E44TA and the twin-turbo 12-4E-E44TTA.

Cummins introduces four new EPA Tier-4 Interim and EU Stage IIIB emissions-meeting engines. The next generation of 4-cylinder QSB3.3 and QSB4.5 engines are designed for compact equipment. The QSX11.9 and QSX15 engines range from 300 hp to 600 hp. The XPI system is complemented by a single Cummins turbocharger able to continuously vary airflow boost to match engine rpm and load demands. The units feature a scaled-down cooled Exhaust Gas Recirculation system and Cummins particulate exhaust aftertreatment. The direct-flow air cleaner reduces space claim by up to 35 percent compared with typical Tier-3 filters.

JCB's Ecomax T4 4.4-liter engine, the latest generation of JCB Dieselmax engines, is undergoing in-field testing, the company having focused on meeting Tier-4 interim emission standards without a diesel particulate filter. With second-generation common-rail fuel-injection technology, injection pressures have been raised to 29,000 psi and nozzle-hold geometry has been refined to improve distribution of the fuel within the cylinder. Cooled exhaust gas recirculation is used to clean up exhaust gases before they are passed from the engine.

Kohler Co.

Kohler Co. has upgraded its air-cleaning system functionality on Kohler's Command Pro single-cylinder, horizontal-shaft commercial engines. Kohler's four-stage cyclonic, heavy-duty air filtration system begins with a mesh screen at the air-intake port. Once entered the cleaning chamber, air is circulated in a cyclonic motion to force large contaminants from the engine. Remaining air passes through a reusable foam pre-cleanser to trap midsize particles.

Mystik Lubricants

Mystik's new JT-4 2-cycle lawn and garden engine oil is a synthetic-blend lubricant designed for use in high-performance, air-cooled, 2-cycle engines. Engineered for lower smoke and advanced protection, the formula is designed to offer protection against exhaust port blocking, combustion chamber and piston deposits, ring sticking and scuffing and wear. The oil is pre-diluted to facilitate mixing with gasoline and improved flow in oil-injection systems. Can be used in generators, lawnmowers, leaf blowers, trimmers, chain saws and more.
