Turbocharged direct injection engine is invented by Volkswagen group. TDI identifies all advanced diesel engines using direct fuel injection and a turbocharger. TDI engines are economical and smooth with high levels of torque and good energy efficiency.
Working of TDI
Fuel needs oxygen to burn and the engine has to be supplied with huge quantities of air to get enough. You can solve this problem with a bigger engine - or you can solve it with a turbocharger - as in the TDI. Driven by the exhaust gases, it squeezes air more tightly into the cylinders.
After being drawn through the turbocharger the air is then cooled by passing it through an intercooler, before entering the combustion chamber where diesel is injected directly into the cylinders at very high pressure through a nozzle. It's this intensive mixing of highly atomized fuel with the cooled compressed air that leads to better, more efficient combustion.
Your driving experience is quiet and refined because effective sound keeps noise to a minimum, while hydraulic engine ensure smooth, low-vibration running

Startup
A startup or start-up is a company or project undertaken by an entrepreneur to seek, develop, and validate a scalable business model. While entrepreneurship refers to all new businesses, including self-employment and businesses that never intend to become registered, startups refer to new businesses that intend to grow large beyond the solo founder. At the beginning, startups face high uncertainty and have high rates of failure, but a minority of them do go on to be successful and influential. Some startups become unicorns; that is privately held startup companies valued at over US$1 billion.
Actions
Startups typically begin by a founder (solo-founder) or co-founders who have a way to solve a problem. The founder of a startup will begin market validation by problem interview, solution interview, and building a minimum viable product (MVP), i.e. a prototype, to develop and validate their business models. The startup process can take a long period of time (by some estimates, three years or longer), and hence sustaining effort is required. Over the long term, sustaining effort is especially challenging because of the high failure rates and uncertain outcomes. Having a business plan in place outlines what to do and how to plan and achieve an idea in the future. Typically, these plans outline the first 3 to 5 years of your business strategy.
Design principles
Models behind startups presenting as ventures are usually associated with design science. Design science uses design principles considered to be a coherent set of normative ideas and propositions to design and construct the company's backbone. For example, one of the initial design principles is "affordable loss".
