Small Off-Road Engine (SORE) fuel tanks traditionally have been blow molded in high-density polyethylene (HDPE), but HDPE on its own does not meet the new stringent permeation regulations. Of all commercially available solutions to reach the EPA requirements, monomaterial PA6 technology scores the highest when it comes to the combination of permeability, process stability, mechanical properties, and costs, according to DSM.
Rule mandates lower levels of pollutant emissions from light- and heavy-duty vehicles while also mandating significantly lower levels of sulfur in gasoline to help achieve the emissions reductions.
The new "oil boom" is causing California's air-quality regulators to develop new policies to stimulate the industry's investments in ZEV technologies, and hopefully accelerate hybrid and EV sales, a member of the Air Resources Board told the 2014 SAE Hybrid & EV Symposium audience.
Lubricant performance may not appear to be a salient challenge for EV operation even when it comes to the development of world electric speed record achievements and on-track e-racecars; but it is, says Millers Oils' Technical Director, Martyn Mann.
The WSU team found an edge over the competing designs by employing liquid hydrogen (LH2) storage to maximize station capacity and reduce capital and operating costs. Delivering hydrogen in liquid form reduces the energy used for distribution, and 80-90% of small-merchant hydrogen is delivered via cryogenic liquid tanker truck.
Engineering Events staff at SAE International in Warrendale, Pennsylvania, have extended the call for abstracts through September 21 for the organization’s AeroTech aerospace and defense technology conference, which will take place at the Fort Worth Convention Center in Fort Worth, Texas, March 14-16, 2023.

Using gasoline in modified truck diesel engines can result in more than 50% efficiency if the combustion process is done correctly, according to research conducted at Lund University in Sweden. By employing a partially premixed combustion (PPC) process, fuel consumption for gasoline engines could be cut in half, the researchers claim.
