This document provides an overview of key components and systems on a diesel locomotive. It discusses the introduction of railways in India and describes key locomotive parts like the diesel engine, turbocharger, expressor, couplings, and traction motors. It also explains locomotive classification based on gauge and power. The document aims to introduce the reader to the basic functioning and components that make up a diesel locomotive.
Ppp train history
The document describes four main types of locomotives: steam, diesel, electric, and maglev. Steam locomotives are powered by boiling water to produce steam, while diesel locomotives use combustion engines and fuel similar to cars. Electric locomotives draw power from overhead wires or other external sources. Maglev trains are the fastest, using magnets instead of wheels to glide above tracks without air pollution. The document also mentions identifying locomotives in pictures and having students create projects about their favorite type.
6 stroke engine
The document discusses a six-stroke engine which aims to improve fuel efficiency and reduce emissions compared to traditional four-stroke engines. It works by adding two additional strokes: after the four-stroke cycle is completed, fresh air is drawn in and expelled to capture waste heat for a secondary power stroke. This provides two power strokes per cycle and can increase efficiency by 40% while reducing pollution by up to 65%. However, the engine is more complex with more components and lower power per cylinder compared to four-stroke designs. Widespread adoption in automobiles could significantly reduce fuel use and emissions globally if efficiency gains are realized.
presentation on diesel locomotive works (dlw)
Diesel Locomotive Works (DLW) in Varanasi manufactures diesel-electric locomotives for Indian Railways. It was established in 1961 in collaboration with ALCO, USA. DLW's annual production is 25 locomotives. The latest locomotive it produces, the WDG5, has a capacity of up to 5,500 HP. DLW supplies locomotives not just to Indian Railways but also to other countries and industries. It uses various machines like conventional, NC and CNC for manufacturing locomotives.
Locomotive
The document discusses the key components of a diesel locomotive. It states that the diesel engine powers the locomotive and can rotate at up to 1,000 rpm, turning the alternator's shaft. The alternator then generates electricity which is used by the traction motors to power the wheels of the locomotive. Some of the main components discussed include the diesel engine, alternator, traction motors, electronic controls, batteries, and various cooling and air systems.
6 stroke engine
Bhagawan Upreti presented on the six stroke engine. The six stroke engine adds two additional strokes to the traditional four stroke engine cycle to improve efficiency and reduce emissions. It captures waste heat from the four stroke cycle to power an additional exhaust and power stroke. This increases efficiency by 40% over a four stroke engine. Modifications are made to the crankshaft, camshaft, valves and timing to accommodate the extra strokes. While advantages include reduced fuel consumption and emissions, challenges include withstanding thermal stresses and needing separate water tanks for injection. Further development is ongoing to address issues and commercialize six stroke engine technology.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
