There are two options on offer. One is a conventional looking guard while the other is a more compact metal one that sits between the engine exhaust and front part of the crankcase. Both can be had in either matte black or stainless steel finish.

Based on fuel injection system, the multipoint fuel injection system segment is anticipated to hold a leading share of the diesel fuel injector market due to efficient combustion of the fuel in the combustion chamber in order to produce required power. Arrangement of fuel injectors in different ways leads to variation in output of the engine. This, in turn, is anticipated to boost the segment at a significant growth rate during the forecast period.

Specifically, to get the fuel-oxygen mixture right, the system requires two oxygen sensors, one each to detect the engine’s catalytic converter input and output exhaust oxygen concentrations. Along with other sensor data, the vehicle’s powertrain control module (PCM) takes input from the oxygen sensor and the engine to calculate and dynamically adjust the engine’s fuel-oxygen ratio.

The jump to direct injection was a bit of a learning curve for most auto manufacturers. Due to the inhomogeneous blending of air and fuel at low engine speeds, controlling engine emissions has become harder. Think of a mist sprayer (port injection) versus a pressure washer (direct injection). Even when using the intake manifold’s charge motion control valves to increase port velocity at lower engine speeds, the fuel was effectively spraying through the air and causing inconsistent air/fuel ratios.

The three new powertrains have been developed through the Renault-Nissan-Mitsubishi Alliance. By using the strength and resources of the Alliance, Nissan can deliver synergies which push the boundaries of what is possible from a three-cylinder turbocharged petrol engine. Each offers the highest levels of performance and refinement to customers, meets the strictest standards of reliability and durability as well as reduced CO2 emissions.

Andrew McDonald • There are so many different types of vehicles on the road, and so many variations in engine choices in one model of vehicle, it can be confusing to the everyday motorist to decide on the appropriate fuel.

The emergence of nanotech also has reshaped the design and manufacture of air filters, but unlike fuel and oil filters, air filters become more efficient over time. They are designed to form a “dust cake” to remove finer and finer particles, making them increasingly effective “right up until they reach a ­level of restriction high enough to necessitate a change,” said Ken Hanover, director of North American aftermarket sales for Cummins Filtration Inc.

I made it home from quite a ways back on a public access road in a National (US) Forest by using my bootlaces to replace the broken throttle cable. Removed tc assembly and routed the laces through the hole in the firewall. Neat part was that on those 80s Ford trucks the cruise control used a separate cable. All I had to do was use my new hand throttle to get back to pavement and then I could use cruise to give my hand a rest. I did have to buy a new tc the next day, but at least I didn’t have to walk out 12+ miles to pavement.

The new generation KTM 250 XC-W TPI is the ultimate combination of power and rideability. It has been completely reworked for 2020, featuring a new frame with optimized flex characteristics, a new innovative 3D stamped exhaust offering improved impact resistance and reduced noise levels and updated premium WP suspension for unmatched performance in extreme terrain. Setting a clear benchmark for intuitive handling, unique style and top performance thanks to its innovative TPI (transfer port injection) system, this updated machine clearly demonstrates KTM’s unrelenting commitment to 2-stroke development. Excellent fuel efficiency, clean exhaust emissions and the benefit of not having to play with jetting out on the trail make TPI technology a rider favorite, and with new mapping and an additional ambient air pressure sensor to improve altitude compensation, the updated KTM 250 XC-W TPI continues to reach new heights in offroad competition.

Back in the glory days, Ford’s FE engine was quite a performer in NASCAR, sports car racing, and at drag strips all across America. While Ford’s more exotic Boss 429 or Cammer engines are still celebrated, it is the “not-quite-a-big-block” FE that did yeoman’s work throughout the ’60s. In 1966, in fact, an FE was stuffed between the frame rails of the GT40 that won the 24 Hours of Lemans.

Now Kia is acknowledging that the engine replacements “may not have been properly performed in all cases by Kia dealers,” according to a company statement issued Wednesday but dated Jan. 11. The high pressure fuel pipe may have been damaged, misaligned or improperly tightened while the engines were being replaced, the statement said. That can allow fuel to leak and hit hot engine parts, causing fires.

Way out side of the traditional corn belt here in western NY. They still grow plenty of corn though and only a handful of stations carry ethanol free gas. I seek them out for my boat, motorcycle and power washer gas. It’s about 35 cents a gallon higher than basic unleaded with 10 percent corn juice.
