6 DURABILITY AND PERFORMANCE FOR THE OIL & GAS MARKET Built for the harsh environments found in oil and gas fields, the versatile and powerful family of Kubota natural gas engines share many of the same components found in their venerable, heavy-duty industrial diesel counterparts. Durable, versatile and flexible, these engines are designed and warranted for wellhead gas operations, and they reliably power artificial lift systems, vapor recovery units, compressors, generators and many other applications - with either natural gas or propane. When you count on continued production, count on Kubota. Ask your distributor about the right engine for your operation. Zero-Maintenance Valve Timing Control Standard on Kubota WG15, WG23 and WG38 engines, the rugged helical front gear train is zeromaintenance, heavy duty valve timing control. It is superior to timing belt or chain designs, which require regular maintenance and can lead to major engine failure. Water-Resistant Ignition-System Connectors For trouble-free operation in all climates, the state-ofthe-art ignition system includes tough, water-resistant connectors to ensure an easy startup, day after day. Premium Valve Materials with Cast Iron Cylinder Head High-temperature alloy exhaust valves and seats are fitted into our robust cast iron cylinder head for even more reliable engine life. These wear and corrosion-resistant parts are especially important for wellhead duty. Manufacturer of Record Kubota is the manufacturer of record for this family of engines. The benefit to the customer is having a turnkey solution. In fact, Kubota emission levels for this engine line are lower than US EPA/CARB Phase 3 certified limits an important factor in engine selection since more stringent regulations than EPA or CARB exist in some California Air Quality Districts and Nonattainment areas throughout the United States. Knock Protection A knock sensor in WG15, WG23 and WG38 engines protects from damage caused by detonation or knock caused by fixed spark advance. The sensor detects detonation through mechanical vibration in the engine block, cylinder or head. It sends instant feedback to the ignition system in order to retard spark, reduce knock intensity and protect the engine. Coil-On-Plug Ignition The coil-on-plug design on Kubota WG15, WG23 and WG38 engines eliminates spark plug wires, increasing reliability and lowering your maintenance costs. Kubota spark plug replacement intervals are 2, hours. Two-Year, 2,-Hour Limited Warranty Rest easy knowing your Kubota engine is backed by the manufacturer against defects in materials and workmanship for two years or 2, hours, whichever comes first.
