El motor de inyección directa turboalimentado es inventado por el grupo Volkswagen. TDI todos los motores diésel avanzados que utilizan inyección directa de combustible y turbocompresor. Los motores TDI son económicos y suaves con altos niveles de par y buena eficiencia energética.
Funcionamiento de TDI
El combustible necesita oxígeno para quemarse y el motor debe recibir grandes cantidades de aire para obtener suficiente. Puede resolver este problema con un motor más grande, o puede resolverlo con un turbocompresor, como en el TDI. Impulsado por los gases de escape, aprieta el aire con más fuerza en los cilindros.
Después de pasar a través del turbocompresor, el aire se enfría pasándolo a través de un intercooler, antes de ingresar a la cámara de combustión donde se inyecta diesel directamente en los cilindros a muy alta presión a través de una boquilla. Es esta mezcla intensiva de combustible altamente atomizado con el aire comprimido enfriado lo que conduce a una combustión mejor y más eficiente.
Su experiencia de conducción es silenciosa y refinada porque el sonido efectivo mantiene el ruido al mínimo, mientras que el motor hidráulico garantiza un funcionamiento suave y con pocas vibraciones
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".
