Dam Safety 2. 01. Conference Program by ASDSODam Safety 2. Emulator Unblocked. Conference Program   Published on Sep 4, 2. The official conference program for Dam Safety 2. September 1. 3 1. Outboard Engine Evolution  from Portable to DigitalLife can only be understood backwards but it must be lived forwards. Sren Kierkegaard. Turns out that life is similar to an outboard engine. Only when we look all the way back to this past centurys turn can we really understand how far weve come with todays digital integration, computer controlled internal combustion technology and superior power to weight ratios. You dont have to be an engineer to grasp the basics. Of course it helps if you have a little curiosity and fascination. Thats likely what skilled Wisconsin machinist Ole Evinrude had when he created the first commercially viable Detachable Row Boat Motor in 1. That 1. 5 horsepower, single cylinder motor worked off dry cell batteries. Automatic Process Control By Eckman' title='Automatic Process Control By Eckman' />Ole cranked it by hand to start, rotating a knobbed flywheel. In the 1. 08 years since, many outboard engine companies have come and gone. In 1. 94. 7, for instance, 1. Evinrude in the United States, the company says. But Evinrude and four other major manufacturers Mercury 1. Honda 1. 96. 4, Suzuki 1. Original Article.

Yamaha 1. 98. 3 eventually emerged in this country, pushing each other to innovate and dominate the American marine market. Ole Evinrudes World. While all early outboard engines could be classified as two strokes, all current Evinrude E TECs are also two strokes. The company has chosen to redefine two stroke technology rather than switch to four stroke design. How Backyard Baseball Became a Cult Classic On the beloved computer games 20th anniversary, its creators detail crafting a cast of fictional children, Pablo. INTRODUCTION. One of the major concerns of many countries today is that there is a mismatch between graduates skills, acquired from higher education institutions. Two strokes traditionally offered lightweight power, but the older models also lacked fuel efficiency and discharged environmentally damaging smoke and oil. The basic difference between two and four stroke engines A two stroke completes its cycle with only two movements one up, one down of the piston during one crankshaft revolution a four stroke requires four piston movements during two crankshaft revolutions to complete a power cycle. With the current E TEC G2 two stroke technology, however, Evinrude vastly improved on the original concept. But that didnt happen overnight. Through the mid 1. Evinrude and others struggled to develop outboards that topped 1. In 1. 95. 6, Mercurys Mark 7. Even so, in 1. 96. Evinrudes four cylinder Starflite II set a speed record of 1. The company followed that innovation with push button electric shift. Bigger and Faster Outboards. In 1. 97. 5, the first V 6 outboard engines Evinrudes 2. Mercurys 1. 75 finally scaled the 1. There were certainly big sterndrives and inboard engines before then, says Jason Eckman, Evinrude global product manager. But if you wanted an outboard, you were stuck at a lower horsepower. Greater horsepower paved the way for larger outboard powered vessels, jump starting the era of recreational boating and fishing for a more diverse cross section of Americans. Leaps and bounds occurred during the 1. Evinrudes Ficht technology and Mercurys Orbital DFI. At the same time, the Environmental Protection Agency released its emissions standards for outboards and designated a phase in regulatory approach. But in 2. 00. 0, Evinrudes parent, Outboard Marine Corporation, filed for bankruptcy. Bombardier, a Canadian transportation and aerospace company, bought the assets and rolled out Bombardier Recreational Products outboards in 2. Mostly, carbureted two strokes had to be replaced, Eckman says. Some companies chose to go to four strokes rather than innovate with two strokes, but we already had expertise in two strokes with snowmobiles. Our customer prefers the two strokes power to weight ratio and added midrange torque. It made sense to continue to invest in that technology, to meet and eventually exceed the EPA requirements without taking away that torque and fuel economy. In 2. Evinrude launched E TEC, the next generation of two stroke, direct fuel injection technology with the same block as previous two strokes but with a new cylinder head designed to accept the fuel injector. With direct injection, we can change the timing of the fuel injection. During idle, you dont need the cylinder to be completely full of fuel and air you need only a little. By injecting fuel directly into the cylinder, we can be more precise. Second Generation Evinrude E TECs. Evinrude continued to enhance its technology and drive larger E TEC outboards to market. The company even won an EPA award in 2. In 2. 01. 4, the company launched its second generation of E TEC outboards, the G2s the first time BRP has designed an engine block from scratch to be optimized around direct injection, Eckman says. The main thing was to perfect the combustion by optimizing the air flow. The way the air and fuel mix inside the cylinder to get a perfect ratio, and then the timing of the exhaust so no fuel escapes Its almost like a musical instrument. The G2 stands out in multiple ways. BRP integrated power steering into the engine to offer a better piloting experience, and though the concept had been done before the company mounted the oil reservoir inside the cowling to save space. BRP also added i. Trim, a system that automatically trims the outboard based on load and rpm, and customizable color panels to match the engine with the hull. Although Mercury Marine introduced its first outboards in 1. That side by side development gave Mercury expanded capabilities. After its first six cylinder outboard debuted in 1. Tower of Power, Mercury followed in 1. V 6 outboards the 2. L 1. 75 hp Black Max Merc 1. Carl Kiekhaefer called the meanest, toughest, most beautiful machine weve ever built. The Black Max used power porting, a piston design that provided an additional source of fuel and air that increased horsepower without additional new parts. Mercury delivered the first recreational electronic fuel injection in 1. V 6 2. 20 XRi. EFI also ushered in the first electronic control modules essentially a computer brain to outboards. In 1. 99. 6, Mercury continued its two stroke evolution with the direct injection Opti. Max. The DFI technology helped Mercury meet the new EPA emissions requirements. Opti. Max featured a unique air assist injection system that employed an air compressor and a lower pressure fuel injector rather than a high pressure liquid pump, says David Foulkes, Mercurys head of product development and engineering. Supercharged Mercury Verados. Optis mixed compressed air with fuel, blasting it into the combustion chamber. The fine fuel atomization achieved with that system allows Opti. Max engines to burn diesel and jet fuel as well as. Foulkes says. As conventional two strokes began to raise emissions red flags at the EPA in the 1. Honda and Yamaha rolled out 1. Mercury introduced its Verado platform in 2. Mercury Outboard Tech Advances. Supercharging allows Mercury to reduce the displacement 2. L for Verado 2. 00 to 4. In the past decade, Mercury has completed its full four stroke product line all the way up to the Racing 4. Verado. In addition, Foulkes notes that larger Verados, which use in line six powerheads, are narrow engines that fit on 2. That allows large center console builders to pile as many as five outboards on a transom. Along the way, Mercury has also developed several new materials such as its proprietary anticorrosive alloys as well as some unique systems like Advance Midsection AMS on Verados. AMS reduces the transmission of engine vibration to the boat by cradling the engine around its midsection.
