There are many excellent reasons why Goscor Power Products’ premium product range for agriculture and construction is powered by Robin Subaru engines. “In addition to their superior quality and rugged reliability, these heavy duty overhead cam  engines present a long list of exceptional and unique features that deliver exceptional performance, low operating costs, low maintenance and long life,” notes Mark Bester, General Manager of Goscor Power Products.

Bester explains that the Ex-Premium Subaru industrial engine series is in fact the renowned Robin engine which is known to the local market for delivering superior quality and rugged reliability for close on three decades.

The Subaru industrial engine comes out of the same stable as the Subaru passenger vehicle engine and incorporates the same state-of-the-art forward thinking technology as its counterpart. The sophisticated air-cooled, four-cycle, slant single cylinder engine surpasses the industry benchmark for same sized engines and owes this acclamation to its utter simplicity. The OHC system is chain-driven and makes use of much fewer parts which spearheads a host of advantages. “For instance, problems with valve timing or push rod seal leaks are eliminated as there are no push rods. The oval type case-hardened steel link chain enhances performance and resists stretching for extended maintenance-free operation.” Bester adds that a 2dBA reduction in mechanical noise makes it one of the quietest engines in its class.

Engine life is directly related to temperature and lubrication. The highly efficient cooling system and precision lubrication system on the Robin Subaru engine from Goscor Power Products extend engine life by addressing the two main causes of engine seizure - excessive heat and under-lubrication.

A cooler engine keeps the oil cool, maintaining the right viscosity for maximum engine protection. Cooler oil also lasts longer which extends service intervals. Large cooling fins engineered into the crankcase cylinder and mounting base remove heat generated inside the engine. The heat is dispersed outside using the flywheel mounted at the back of the engine. Further cooling is achieved by the flywheel which runs at high speed and blows over the engine and fins. The result is a 30% cooler engine which Bester says is lower than any similar sized engines currently available in the market.                      

Moving on to the lubrication system, Bester explains that the Robin Subaru engine is fitted with a unique and superior oil pick up system. “So even when operating at a slant, engine efficiency will not be compromised because the system will continue to put oil on the chain.” The engine is also fitted with a unique oil sensor which, unlike an alert sensor which only works during start-ups to warn of insufficient oil in the crankcase, operates while the engine is running. The sensor will pick up on the slightest drop in the oil level and trigger the automatic switch-off, avoiding potential engine seizure. Bester points out that these features can save the engine in applications where, for example, a pump placed next to a river bank may shift down the embankment during operation.

The direct drive through the chain ensures 50% easier, reliable starting, less pulling force and no kick back due to the sophisticated mechanical compression release system and a newly designed combustion chamber. This also extends the life of the recoil starter. Bester highlights that these engines started instantly during testing in temperatures ranging from as low as – 10ºC up to + 50ºC.

The Robin Subaru engine delivers power and performance without compromising on economical fuel consumption. The EX27-Premium 6.0 HP engine, which is the flagship in the range, delivers up to 4.4 kW. The Pentroof combustion chamber includes intake and exhaust valves located at an optimum angle which ensure not only high speed but also homogenous combustion. The positioning of the spark plug directly above the piston ensures even combustion across the piston. In addition to enhancing operational and fuel consumption efficiency, this complete combustion of the fuel also reduces emissions; the environmentally friendly Robin Subaru engines compliant with all USA emission regulations.

With four models available in the Ex-Premium range, the Robin Subaru engines are more than a match when it comes to powering high pressure, clear water and trash pumps to meet a wide range of agricultural applications. “In addition to liquid fertilizer, irrigation, boom spraying and cattle dipping pumps, we also offer a range of heavy duty high pressure firefighting pumps which can be supplied complete with a 620 or 1000L capacity tank,” comments Bester. “Our heavy duty high pressure cleaning pumps take care of virtually any cleaning application on the farm from chicken runs and cow sheds to farm implements and equipment.”

For their size and capacity, the Robin Subaru engines outperform other engines in the same class across-the-board, delivering powerful, reliable and efficient performance accompanied by low operational costs and long life. “The low total cost of owning a Robin Subaru engine realises a return on investment in no time,” concludes Bester.

The Robin Subaru engine is also at home in the construction industry, efficiently powering a wide range of equipment including rammers, rollers, concrete mixers, concrete vibrators, etc. The Robin Subaru engine is available from Goscor Power Products based in Kempton Park, Johannesburg, supported by a countrywide network of distributors.
