kets and the robust gas compression markets. By 2020, nearly 30% of Cummins high-horsepower engine production will be natural gas due to its increasing abundance and low cost. We are putting plans in place now to be ready with reliable and durable products well ahead of the increased demand for gas power. Tier 4 Final emissions above 751 hp (560 kW) give us an opportunity to once again demonstrate technology leadership both in our new family of engines and in our current range to over 4000 hp. As the first engine manufacturer to publicly reveal our technology solution to meet U.S. EPA Tier 4 Final for high horsepower, Cummins plan is to make complex emission solutions simple. Our proven selective catalytic reduction (SCR) technology will be added for Tier 4 Final. Cummins has over a quarter million smaller engines with SCR technology operating around the world today. Our solution is simple, requires little to no redesign work by replacing the existing exhaust muffler, and most importantly, delivers on the fuel efficiency demand we hear from our customers. Tier 4 Final will deliver 5 to 10% improved fuel efficiency, depending on equipment duty cycle. Customers are asking for more, whether its horsepower, natural gas, or upcoming emissions

In a first for Cummins, its new family of QSK95 engines was designed for natural gas from the inception of the program. New V12, V16, and V20 gas engines will see applications in power generation and robust gas compression markets. hurdles. Engine manufacturers need to listen to customers’ changing needs to stay competitive in the future.

2013 taurus gets major powertrain upgrades
The Taurus is Ford’s D-segment (large) flagship sedan, and market competitive forces mean that the car that was new in the 2010 model year gets a major upgrade for 2013. That includes the first North American application of the 2.0-L four-cylinder EcoBoost in a Ford passenger car and important transmission changes. The Taurus is built on a 112in (2845-mm) wheelbase, and overall length is 202.9 in (5154 mm). The 2.0-L EcoBoost gives the Taurus an automatic transmission model with a window sticker that will carry a 31-mpg highway number, just over the magic 30. The city number has not yet been announced. The engine is a direct-injected turbo rated at 240 hp (179 kW), 270 lb·ft (366 N·m), with a fuel injection system that operates at 2200-2800 psi (15.219.3 MPa). The injectors are a seven-hole design and are capable of up to three sequential injections per cycle. The exhaust manifold is integrated into the cylinder head. This EcoBoost edition’s air intake was redesigned for an end entry vs. the previous center entry. This
