Vanguard single-cylinder engines feature a single lever, the company’s proprietary TransportGuard system, which simultaneously shuts off fuel and the ignition. This feature is designed to eliminate human error, keeping fuel where it belongs during transport and preventing fouled plugs, hydraulic lock, cylinder wash down or crankcase oil dilution.
The 4-cylinder QSF2.8, QSF3.8 and QSB4.5 engines are certified to meet U.S. Environmental Protection Agency Tier 4 Final low-emissions regulations. They are designed for compact installation packages for space-constrained construction and material handling equipment across the 49 hp-to-173 hp (37-129 kW) output range. The engines utilize filter-free, flow-through exhaust after-treatment systems and a clean-combustion formula focused on fuel efficiency.
Featuring six models, the V-Twin engine line offers both horizontal and vertical shaft configurations for a greater range of utility. The new V-Twin engine models, which include the GX630, GX660, GX690, GXV630, GXV660 and GXV690, have been designed to offer more power, high fuel economy, low noise, low vibration and low exhaust emissions without the use of a catalyst. The engine’s design along with a 36-blade, low-noise resin-cooling fan, improves cooling efficiencies. Other technologically advanced features include the hemispherical combustion chamber design, higher compression ratio, increased displacement, and steel connecting rods.
John Deere Power Systems introduces five new PowerTech 2.9L generator-drive engines with power ratings from 31 to 55 kW (41 to 74 hp). The new series offers customers a range of compact, emissions-compliant choices for prime-power or standby applications. The PowerTech 2.9L generator-drive engines include models that meet Final Tier 4, Interim Tier 4, and Stage III A emissions regulations; non-emissions certified models are also available for non-regulated markets and stationary applications in the EU.
John Deere PowerSight, a new technology solution for John Deere diesel engines installed in OEM equipment is designed to provide reliable uptime and low cost of operation in rental applications. PowerSight features four John Deere technologies — the JDLink machine monitoring system, machine health prognostics, remote diagnostics and programming, and the PowerAssist app — that integrate to help customers manage their John Deere-powered OEM equipment. The technology solution is available for John Deere Final Tier 4/Stage IV, Interim Tier 4/Stage III B and Tier 3/Stage III A engines.
The Kohler 3.4 Liter KDI 3404 is a Tier 4 Final emission-compliant engine that achieves clean combustion, optimized fuel consumption and enhanced power without the use of a diesel particulate filter via a direct injection system, cooled exhaust gas recirculation and diesel oxygenated catalyst. A high-pressure common rail system is also integrated, which utilizes pressures at 2,000 bar (29,000 psi) to deliver better atomization of fuel, improved fuel consumption and a reduction in emission particulates. The KDI 3404 is available in four ratings, ranging from 74 to 134 hp (55.4 to 100 kW) with peak torques from 276 to 369 lb. ft. (375 to 500 Nm).
Perkins new 404F-E22TA, an engine designed to meet U.S. EPA Tier 4 Final/EU Stage IIIB emissions standards. The addition of a common rail fuel system and full authority electronics offer flexibility in tailoring the engine to specific applications. It also allows for smaller displacement in machines where traditionally housing engines up to 2.9 liters. Performance from the 404F-E22TA has been boosted to 67 hp (50 kW) with a maximum torque of 208 Nm at 1,800 rpm, while rated speed is up to 2,800 rpm. OEMs also have the option of a turbocharged non-aftercooled model, offering up to 48 hp (36 kW).
The 35-horsepower EH90 and 40-horsepower EH99 are 999cc and feature heavy-duty connecting rods, large crankshaft bearings and three-ring pistons. The hardened exhaust valve and seats are designed to handle high temperatures, improving engine performance, efficiency and overall life. The engines include a unique temperature sensor that monitors the engine operating condition and sounds a loud alarm to warn the operator if the engine overheats. Both models are equipped with a low-pressure sensor that prompts an automatic engine shutoff when oil pressure gets too low. A pressurized lubrication system also allows the overhead valve engine to use an automotive grade spin-on oil filter.
