Effect of Secondary Air Injection in Redesigned Exhaust Pipe of Two-Stroke Internal Combustion Engine
Abstract: The emission produced by two-stroke internal combustion engine is not under the limits of vehicle emission norms mentioned by pollution department. An experimental study was performed for more fundamental understanding of effect of secondary air injection on exhaust emissions of two-stroke cycle engine during cold starting period by redesigning the exhaust pipe. The pressurized secondary air is injected in the newly designed exhaust pipe near the exhaust port with the …

TurbochargedTwo-Stroke SI Engine as Back-up Range Extender for Battery Electric Vehicles
Abstract: Installation studies indicates that a compact single-cylinder two stroke Spark Ignited (SI)-engine with a swept volume of 400-500 cc is small enough to install in the heavy-duty Battery Electric Vehicle (BEV) application considered here. Four-stroke engines of similar power to the two-stroke engine would need additional installation volume because of the larger cylinder heads, bulky oil pans and the need for more cylinders to create the same number of power-pulses …

Optimisation of Ratio of Center Distance of Adjacent Hole to Diameter of Pre-stressed Holes by FEA
Abstract: Residual compressive stress zone around a fastener hole is introduced by a process called pre-stressing. This is being done to reduce adverse effect of cyclic tensile stress and to restrict the fatigue crack growth due to material flaws or imperfect surfaces. The objective of this investigation is to optimize the inter-hole distance between adjacent cold expanded holes on a plate restricting the deformation of material between holes to the elastic …

Sub-structure Geometry Effect on Energy Absorption Ability of Hierarchical Honeycomb under Crushing
Abstract: Honeycomb structures are stiff and light weight composite structures which show good energy absorption. Hierarchical honeycomb structures which are bio-inspired innovative form of honeycomb structure, are used for energy absorption applications. The crashworthiness of hierarchical honeycomb structures is function of sub-structure geometry. In the present investigation, crushing of vertex based hierarchical honeycomb with regular polygonal (n=3, 6, 9, 12, 15) and circular substructures is analysed using nonlinear explicit finite element …

Cardiovascular Disease is the Most Common Cause of Diabetes Mellitus, But Massage Therapy is Very Effective for Patients Who Are Suffering From Cardiovascular Disease With Diabetes Mellitus
Abstract: The cardiovascular system is a part of the larger circulatory system, which circulates blood throughout the body. When circulation of capillaries deliver oxygen and nutrients in obstructive manner, then pressure of arteries increase and it convert into high blood pressure. Patients having both hypertension and diabetes, which is a common combination, their risk for cardiovascular disease doubles. There are many benefits of massage therapy for people with diabetes and heart …
