## Internal Combustions/Thermodynamic Review questions

Internal Combustions/Thermodynamic Review questions. Hi, I need these questions thoroughly solved that satisfy the requirements within 2 days. Please show your steps for the calculations and answer each question with a proper explanation. Work can be shown by hand or typing as long as it is legible!Here are the questions (the questions will be underlined to differentiate them from the information provided by each question prompt):1. A famous inventor proposes a new engine concept to control engine load without throttling. To achieve efficient operation at part load, the concept uses late intake valve closing which effectively creates an expansion ratio larger than the compression ratio. The engine is four-stroke, spark ignition and operates unthrottled. The engine has a clearance volume of 300 cm3 and a displaced volume of 2700 cm3 per cylinder. The fresh working fluid is a lean mixture of methane (CH4) and air at an equivalent ratio = 0.8. The lower heating value of methane is 50 MJ/kg.The cylinder contents behave as an ideal gas with constant specific heats (y = 1.25, R = 300 J/kg-K). The cycle processes are described below: Intake Process 5-6-1 For the first part of the process (5-6), the piston moves from top dead center (TDC) to bottom dead center (BDC). For the second part of the process (6-1), the piston moves up to half-way into the compression stroke while the intake valve is still open. Throughout the intake process (5-6-1), the fresh fuel air mixture is inducted into the cylinder and mixed with residual gas, while the cylinder pressure remains constant at 100 kPa. When the intake valve is closed (State 1), the temperature of the cylinder contents is 440K. Compression Process 1-2 Compression is reversible and adiabatic. The gas pressure rises as the piston moves towards TDC. The “compression” rc is defined as the ratio of the cylinder volume at the intake valve closing to clearance volume. Combustion Process 2-3 The mixture is ignited with a spark and releases the fuel chemical energy at the TDC position. The “gross” heat released by the fuel during the constant volume combustion process is accompanied by considerable heat loss to the engine walls. The “net” heat release raises the temperature and pressure of the working fluid. Expansion Process 3-4 The combustion gases follow a reversible and adiabatic expansion process from TDC to BDC, until the cylinder pressure drops to the exhaust pressure (100 kPa) and the gas temperature drops to 800K. The “expansion ratio” re is defined as the ratio of cylinder volume at exhaust valve opening (State 4) to clearance volume. Exhaust Displacement Process 4-5 With the exhaust valve open, the piston moves from BDC to TDC while the exhaust gas is displaced out of the cylinder at 100 kPa. The exhaust valve closes at State 5. (1.1) Draw the cycle on a p -V diagram, clearly showing all relevant states and processes. (1.2) Determine the residual fraction when the exhaust valve is closed. (1.3) Determine the total mass of the cylinder contents and the mass of fuel when the valves are closed. (1.4) Determine the compression ratio, rc, and the expansion ratio, re. (1.5) Determine the magnitudes of the peak temperature and pressure in the cylinder. (1.6) Calculate the gross heat released by the fuel during combustion process and the heat losses to the walls. (1.7) Calculate the gross-indicated, pumping, and net-indicated work transfers of this cycle. (1.8) Calculate the gross-indicated and net indicated fuel conversion efficiencies of this cycle. (1.9) Calculate the net indicated power of a four-cylinder engine at 7200 RPM. (1.10) The inventor claims that the timing of the closing of the intake valve can be varied to control engine power output without throttling. When should the intake valve be closed for a maximum output equivalent to wide open throttle (WOT) in a conventional design? State physical arguments, but do not repeat any of the calculations! Briefly comment on the potential of the concept. 2. It has been shown that blending hydrogen (H2) and carbon monoxide (CO) with hydrocarbon fuels, n-Octane (C8H18) in this case, can improve the lean limit of spark ignited engines. Assuming that the fuels are all in the gaseous phase, the Lower Heating Value of n-Octane (C8H18) is 44,788 kJ/kg, the Lower Heating Value of CO is 10,100 kJ/kg, while the Lower Heating Value of hydrogen (H2) is 119,953 kJ/kg. On a volume basis the fuel mixture consists of: 25% n-Octane (C8H18), 25% carbon monoxide (CO) and 50% hydrogen (H2) Fuel and air enter the engine at standard state conditions (1 atm, 25⁰C). The mass flow rate of air into the engine is 200 g/sec, while the equivalence ratio is 0.5. The heat losses from the working fluid to the engine coolant and the environment are 50 kW. The temperature of the combustion products in the exhaust manifold is 900 K. (2.1) Determine the overall combustion reaction for this engine’s fuel mixture using atmospheric air (O2 3.76 N2). Normalize to a per mole fuel basis. (2.2) The molecular weight of the fuel mixture. (2.3) Calculate the air-to-fuel ratio (mass based) at which this engine is operating. (2.4) Calculate the fuel mass flow rate. (2.5) Calculate the lower heating value per kg of fuel. (2.6) Calculate the higher heating value per kg of fuel, where hfg, H2O = 2442 kJ/kg (2.7) Determine the net indicated power output of this engine in kW (2.8) Determine the fuel conversion efficiency of this engine.

## Project Specificatio

Project Specificatio. Battery powered home heating

Heat pumps are e low carbon approach space heating, but they use electricity, which is much more expensive than gas per kwh One solution is to use cheap electricity at night store it in a battery (such as e Tesla Powerwall) and use this to run the heat pump when the heat needed. This project examines the cost effectiveness of this strategy as the prices of batteries and heat pumps falls.

Deliverables

In this section the submission requirements will be discussed. The weighting for each component is clearly presented in section. It should not be much than 3 to 4 pages

Specification

After some initial contact with the project supervisor, the student will prepare a document called “Project Specification”. This document will set the scope and an initial schedule for your project, which will help you greatly throughout the course of the project period. The aim of the specification is to have a clear, succinct overview of the project with aims and objectives together with work package breakdown. This will help you to structure/plan your work and keep an eye on progress over the period. Consequently, below is a suggested structure that could be followed:

The title of your project

Candidate name

Introduction a brief description of your project to explain what your project is about.

The aim of your project

The objectives of your project (to reach the aim)

Deliverables – a brief description of the anticipated outcomes from undertaking this project.

Work package breakdown.

A Gantt chart showing the planned timeline and milestones/deliverables as appropriate.

As for the Gantt chart dates, the starting date is 1/11/2021 to 17/12/2021Requirements: please follow the Rubric file | .doc file
