Dnyanesh Sapkal joined Achates Power in October as vice president of engineering. In this role, he is responsible for the overall design, analysis and mechanical development of the Achates Power opposed-piston, two-stroke engine hardware. He also manages a team of engineers to ensure the product design robustness by utilizing modern analytical tools and demonstrating results through dynamometer testing.

Sapkal has 27 years of light- medium- and heavy-duty powertrain design experience, along with 17 years of experience in diesel and gasoline engine design, and he most recently worked as the department manager of commercial engines and advanced applications design at FEV Inc.

While there, he managed the teams responsible for design and development of various powertrains including gasoline, diesel and dual-fuel engines as well as automotive hybrid transmissions and wind turbine gearboxes.

His tenure at FEV also included positions as a supervisor and senior lead engineer. Prior, Sapkal was the senior design and release engineer at Ford Motor Co. He began his career as an engineering manager at Mahindra in Mumbai, India where he oversaw the design and development of medium-duty diesel engines and also led various product development teams in the powertrain engineering department.

Sapkal is a Six Sigma Green Belt and received his Bachelor of Science in mechanical engineering from the University of Mumbai, where he graduated with honors. Dnyanesh Sapkal.VentureBeat Homepage. Updated Sunday, Oct. The San Diego-based company will use the newly raised capital to continue development and commercialization of its opposed-piston technology, which is intended to significantly improve fuel efficiency for gasoline powertrains.

The engine maker also has a contract with Austrian engineering firm AVL to develop a state-of-the-art combat engine for the U. All five were investors in Achates prior to this most recent funding round. Become a Member Sign In. General Newsletters Got a news tip?

Search jobs and find your dream job today. Get Hired.Achates Power is an American developer of opposed-pistontwo-strokecompression ignition engines for use in commercial and passenger vehicles. According to Achates Power, its opposed-piston, two-stroke engine has demonstrated an increase in fuel efficiency and similar engine-out emissions levels.

The design positions two pistons per cylinder—working in opposite, reciprocating motion. This eliminates parts including the cylinder head and valvetrain, improving overall engine efficiency as these components are considered primary contributors to heat and friction losses.

The two-stroke cycle compounds the efficiency benefits of the opposed-piston engine architecture. With this cycle, each combustion event is shorter in duration and, therefore, closer to optimum timing as compared to four-stroke engines. Two-stroke engines are also smaller in displacement and size compared to four-stroke engines for similar performance. While development of historic opposed-piston engines ceased for use in on-road car and truck applications with the introduction of modern emissions standards[7] Achates Power says that it has patented many modifications to the original architecture [9] in order to meet current standards.

Achates claims that its two-stroke opposed piston engine can achieve lower emissions of nitrogen oxides NOx than an equivalent four-stroke engine for several reasons.

Specifically, the Michigan team of Prof. Heath Hofmann, Dr. Hofmann will develop control algorithms for a commercially available electric machine that will turn an OP Engine into a hybrid OP engine into a series-hybrid, or range-extender for electric vehicles. Siegel and Stefanopoulou will focus on the engine and its interaction with the motor generator.

Early versions of OP Engine, described in this videohave been around sinceand have been used in automobiles, ships, airplanes, and submarines, as well as tanks and trucks. Achates Power has been developing OP Engines that enable automakers to achieve high efficiencies across a wide range of operating conditions.

The plan is to reconfigure an Achates Power OP Engine by attaching two motor generators directly to the crankshafts of the engine, generating electricity directly from the rotational energy of the engine.

The electric motor generator attached to the engine will feed the battery for the range extension, delivering consistent, efficient power to the driveline. There are many different ways to build a hybrid vehicle, and this project corresponds most closely to a series configuration, though with some novel aspects.

Relative path windows

The mechanical crank to crank connection, used to synchronize the intake and exhaust pistons of the OP Engine, will be eliminated and the electric motor generators will provide electrical piston synchronization.

The electric motor generators will also be used to control the position of the piston in the engine, which makes it possible to control its thermodynamic cycle.

These control opportunities are expected to improve the overall fuel efficiency of the engine. Siegel will focus on the real time estimation of the piston motion which is critical for the efficiency as a tight synchronization is imperative; a few degrees error and the pistons will not make sufficient compression to facilitate combustion. Stefanopoulou will derive the piston trajectory that optimizes the thermodynamic cycle based on multi-objective criteria.

One of the tricky parts for Hofmann is to be able to control the instantaneous torque pulses of the pistons with the electric motor generators, which are far less powerful.
